1982年5月11日至14日第九届国际低温工程和国际低温材料会议在日本神户举行。我作为中国代表团的一员参加了会议。现在就这次会议上所了解到的低温材料的发展情况作一简单介绍。一、金属结构材料1.不锈钢奥氏体不锈钢在低温工程中的应用最为普遍。这次会议上关于这类不锈钢在4～300K May 11-14, 1982 Ninth International Cryogenic Engineering and International Cryogenic Materials Conference was held in Kobe, Japan. I attended the meeting as a member of the Chinese delegation. Now I will brief you on the development of low temperature materials learned at this meeting. First, the metal structure of materials 1 stainless steel austenitic stainless steel in the most common application of engineering. The meeting on this type of stainless steel at 4 ~ 300K
