Controlled Thermal Processing, Inc. considers the definition of the process to be: &#8220;The modification of a material or component using cryogenic temperatures.&#8221;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Cryogenic temperatures are defined by the Cryogenic Society of America as being temperature below 120K ( -244F , -153C ). This is different from cold treatments that are often spelled out in heat-treating specifications. Cold Treatments generally only go down to temperatures of 178K ( -140F , -96C ) Cryogenic treatments have been found to offer performance over and above that of cold treatments by studies performed by the Illinois Institute of Technology Research Institute for the US Army Aviation and Missile Command.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The word Cryogenics is derived from the Greek words &#8216;Kryos&#8221; (meaning cold) and &#8220;Genes&#8221; (meaning born)<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Since there is no official definition of the process, the process parameters vary widely from one company to the next. Processes and equipment vary considerably from one company to the next. Simply specifying &#8220;cryogenic treatment&#8221; is not sufficient. One must be very careful when comparing results from one company to those of another. Controlled Thermal Processing, Inc. has been in business for over 20 years. Our equipment is the best available. Where our cryogenic processing machinery use the latest vacuum insulated dewars and heat exchanger technology, we have competitors who pour raw liquid nitrogen on their customer&#8217;s expensive tooling. Our techniques are proven ones. For instance, Controlled Thermal Processing, Inc. processes parts for other &#8220;cryogenic processing&#8221; companies because our process and machinery works where theirs fail.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The process is referred to by quite a few different terms. Terms heard in industry are:<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Cryogenic Processing, Cryogenic Tempering, Cryogenic Stress Relief, Cryogenics, Cryogenic Hardening, Cryo, Cryogenic Treatment, Cryogenating Deep Cryogenic Tempering, Cryotempering, Thermal Cycling, Deep Cryogenic Treatment (DCT) Cryoing .<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">According to Metals Handbook, published by ASM, tempering is &#8220;&#8230;.reheating hardened steel to some temperature below the eutectoid temperature to decrease hardness and\/or increase toughness.&#8221; Tempering used to mean hardening in archaic English, hence the persistence of phrases like &#8220;fine tempered steel&#8221; in advertising. Such a phrase is virtually meaningless, as any hardened steel would be tempered anyway. We feel it is confusing and inaccurate to use the word &#8220;Tempering&#8221; when referring to cryogenic processing. Since the process rarely makes materials significantly harder, the term &#8220;Cryogenic Hardening&#8221; is also confusing, inaccurate, and does not convey the full impact of what cryogenic processing can do. Also, the term &#8220;stress relieving&#8221; also indicates a specific process, and the use of cryogenics covers much more than stress relieving. As far as calling it &#8220;Deep Cryogenic Treatment&#8221;, anyone who is familiar with cryogenic science will know that 300oF is not very deep into the cryogenic range, which starts at -244oF. Is it nit picking to criticize what people call the process? Maybe it is, but fancy sounding names often confuse the issue as to what the process does.<br>Our preference is to call the process &#8220;Cryogenic Treatment&#8221; or &#8220;Cryogenic Processing&#8221;.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Both &#8220;Cryogenic Processing&#8221; and &#8220;cryogenic Treatment&#8221; have been approved by the Cryogenic Processing Subcommittee of the ASM. That&#8217;s good enough for us.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">One term that does not apply to what we do is Cryonics. The word Cryonics refers to the process of freezing living tissue with the intention of bringing it back to life in the future. . We do not have Walt Disney or Ted Williams in the back room.<br>\fTechnicals 2 : D\u00e9finitions<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Il n&#8217;existe aucune d\u00e9finition \u00ab&nbsp;officielle&nbsp;\u00bb de l\u2019expression traitement cryog\u00e9nique. Controlled Thermal Processing, Inc. consid\u00e8re que la d\u00e9finition de ce proc\u00e9d\u00e9 est : \u00ab&nbsp;La modification d&#8217;un mat\u00e9riau ou d&#8217;un composant par des temp\u00e9ratures cryog\u00e9niques.&nbsp;\u00bb<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Les temp\u00e9ratures cryog\u00e9niques sont d\u00e9finies par la Soci\u00e9t\u00e9 Cryog\u00e9nique Am\u00e9ricaine (Cryogenic Society of America) comme des temp\u00e9ratures inf\u00e9rieures \u00e0 120K (-244 F, -153C). Cela est diff\u00e9rent des traitements par le froid tels qu\u2019ils sont d\u00e9finis dans les sp\u00e9cifications de traitement par la temp\u00e9rature. Les traitements par le froid descendent g\u00e9n\u00e9ralement seulement \u00e0 des temp\u00e9ratures de 178K (-140F, -96C). Les \u00e9tudes effectu\u00e9es par l\u2019Institut de Recherche Technologique de l\u2019Illinois pour l\u2019Arm\u00e9e de l\u2019Air et de Contr\u00f4le des Missiles Am\u00e9ricaine ont montr\u00e9 que les traitements cryog\u00e9niques offraient des performances sup\u00e9rieures aux simples traitements par le froid.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Le terme cryog\u00e9nie est d\u00e9riv\u00e9 des mots grecs \u00ab&nbsp;Kryos&nbsp;\u00bb (froid) et \u00ab g\u00e8nes&nbsp;\u00bb ( n\u00e9).<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Etant donn\u00e9 qu\u2019il n\u2019existe aucune d\u00e9finition officielle du proc\u00e9d\u00e9, ses param\u00e8tres varient consid\u00e9rablement d&#8217;une entreprise \u00e0 l\u2019autre. De m\u00eame, les processus eux-m\u00eames et l&#8217;\u00e9quipement varient consid\u00e9rablement d&#8217;une entreprise \u00e0 l\u2019autre. La simple appellation \u00abtraitement cryog\u00e9nique\u00bb est insuffisante. Il faut donc \u00eatre tr\u00e8s prudent lorsqu\u2019on compare les r\u00e9sultats d&#8217;une entreprise \u00e0 ceux d\u2019une autre. Controlled Thermal Processing, Inc. a plus de 20 ans d\u2019exp\u00e9rience. Notre \u00e9quipement est le meilleur du march\u00e9. L\u00e0 o\u00f9 nos machines utilisent la toute derni\u00e8re technologie des vases de Dewar et des transformateurs derni\u00e8re g\u00e9n\u00e9ration, nos concurrents versent de l&#8217;azote liquide brut sur l&#8217;outillage co\u00fbteux de leur client. Nos techniques sont \u00e9prouv\u00e9es. Par exemple, des entreprises de \u00abtraitement cryog\u00e9nique\u00bb sous-traitent des pi\u00e8ces aupr\u00e8s de Controlled Thermal Processing, Inc. parce que notre proc\u00e9d\u00e9 et nos machines fonctionnent l\u00e0 o\u00f9 les leurs \u00e9chouent.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Diff\u00e9rentes terminologies sont utilis\u00e9es pour faire r\u00e9f\u00e9rence au proc\u00e9d\u00e9. Les terminologies les plus usit\u00e9es dans l&#8217;industrie sont :<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Traitement cryog\u00e9nique, Trempe Cryog\u00e9nique, D\u00e9charge Cryog\u00e9nique, Cryog\u00e9nie, Durcissement Cryog\u00e9nique, Cryo, Cryogenic Processing, Traitement Cryog\u00e9nique extr\u00eame Cryog\u00e9natant, Cryotrempe, Cyclage Thermique, Traitement Cryog\u00e9nique extr\u00eame, Cryoing.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Selon le manuel \u00ab&nbsp;Metals handbook&nbsp;\u00bb (en anglais), \u00e9dit\u00e9 par l&#8217;ASM, la trempe est \u00ab&nbsp;\u2026.le r\u00e9chauffement de l&#8217;acier tremp\u00e9 \u00e0 une certaine temp\u00e9rature inf\u00e9rieure \u00e0 la temp\u00e9rature eutectique pour en diminuer la duret\u00e9 et\/ou pour augmenter la solidit\u00e9.\u00bb Tremper signifiait durcir en vieil anglais, ce qui explique la persistance d\u2019expressions comme \u00ab&nbsp;l&#8217;acier tremp\u00e9&nbsp;\u00bb dans la publicit\u00e9. Une telle expression est pratiquement sans signification, puisque tout acier est tremp\u00e9 de toute fa\u00e7on. Nous pensons qu\u2019employer le terme \u00ab&nbsp;trempe&nbsp;\u00bb est impr\u00e9cis et sujet \u00e0 confusion pour parler de traitement cryog\u00e9nique. Etant donn\u00e9 que le proc\u00e9d\u00e9 rend rarement les mat\u00e9riaux plus durs de fa\u00e7on sensible, le terme \u00ab&nbsp;durcissement cryog\u00e9nique&nbsp;\u00bb est \u00e9galement impr\u00e9cis, sujet \u00e0 confusion et ne rend pas justice aux applications possibles du traitement cryog\u00e9nique. En outre, le terme \u00ab&nbsp;d\u00e9charge cryog\u00e9nique&nbsp;\u00bb fait r\u00e9f\u00e9rence \u00e0 un proc\u00e9d\u00e9 sp\u00e9cifique, et l&#8217;utilisation de la cryog\u00e9nie a une port\u00e9e bien plus large que la simple d\u00e9charge. Quant \u00e0 l&#8217;appeler \u00ab&nbsp;traitement cryog\u00e9nique extr\u00eame&nbsp;\u00bb, quiconque a un minimum de connaissances de la science cryog\u00e9nique saura que -300\u00b0F n&#8217;est pas tr\u00e8s extr\u00eame dans la gamme cryog\u00e9nique, qui commence \u2013244\u00b0F. Est-ce chercher la petite b\u00eate que de critiquer les terminologies utilis\u00e9es pour faire r\u00e9f\u00e9rence au proc\u00e9d\u00e9 ? Peut-\u00eatre, mais utiliser des termes fantaisistes et ronflants ne fait qu\u2019ajouter \u00e0 la confusion quant \u00e0 ce que peut accomplir ce proc\u00e9d\u00e9.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Nous pr\u00e9f\u00e9rons appeler ce proc\u00e9d\u00e9 \u00abtraitement cryog\u00e9nique\u00bb ou \u00abcryogenic processing\u00bb.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Les termes \u00abtraitement cryog\u00e9nique\u00bb et \u00abcryogenic processing\u00bb ont \u00e9t\u00e9 approuv\u00e9s par le Sous-Comit\u00e9 de Traitement Cryog\u00e9nique de l&#8217;ASM. Cela nous convient tout \u00e0 fait.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Il existe toutefois un terme qui ne s&#8217;applique pas \u00e0 ce que nous faisons, c\u2019est le terme Cryonie ou Cryog\u00e9nisation. La Cryonie se rapporte au proc\u00e9d\u00e9 qui consiste \u00e0 congeler des tissus vivants dans l\u2019espoir de pouvoir les ressusciter ult\u00e9rieurement. Walt Disney ou Ted Williams ne se cachent pas dans l\u2019arri\u00e8re-salle.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">&#8230;or something like this:<\/p>\n\n\n\n<blockquote class=\"wp-block-quote is-layout-flow wp-block-quote-is-layout-flow\">\n<p class=\"wp-block-paragraph\">Cryogenics improves performance in many realms!<\/p>\n<\/blockquote>\n\n\n\n<p class=\"wp-block-paragraph\"><a href=\"https:\/\/www.gocryo.fr\/privacy.html\" target=\"_blank\" rel=\"noopener nofollow\">Confidentialit\u00e9<\/a><\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n","protected":false},"excerpt":{"rendered":"<p>2 technicals : definitions There are no &#8220;official&#8221; definitions of the term cryogenic processing.
