据Cryogenic s 1982.Vol,22,No8,报导,美国路易斯安娜州工业技术学院R.F.Barron博士对19种不同钢料进行深冷处理(Cryogenic Treatmeat)的试验研究,这19种金属材料包括12种工具钢、3种不锈钢以及4种常用碳钢和铸铁。研究结果表明,经过淬火等热处理的材料以缓慢的冷却速度(3℃/分),从室温降至189K(-84℃)或77K(-196℃),保持24小时,然后再回复到室温。与同类材料相比经过
According to Cryogenics 1982. Vol.22, No.8, it is reported that RFBarron, Ph.D., of Louisiana Institute of Technology, Louisiana, conducted a pilot study on cryogenic treatment of 19 different steels, including 12 tool steels , Three kinds of stainless steel and four kinds of commonly used carbon steel and cast iron. The results show that the material after the heat treatment such as quenching is cooled down to room temperature to 189K (-84 ° C) or 77K (-196 ° C) at a slow cooling rate (3 ° C / min) for 24 hours and then returned to room temperature.
