锰低温钢奥氏体界面元素不平衡儒聚及其脆断机制的研究采用低温和超低温钢时，主要选择对象是镍钢和镍铬奥氏体不锈钢，但由于其资源短缺，价格昂贵，强度不高以及在超低温下会呈现磁性等问题而难以满足要求。从七十年代末起，国内外材料专家大力研究含锰的低温钢，但在研究这
Study on Unbalanced Confucianism and Brittleness Mechanism of Austenite Interfacial Elements in Manganese Low Temperature Steel When low temperature and ultra-low temperature steels are used, the main choices are nickel steel and nickel-chromium austenitic stainless steel. However, due to its shortage of resources, Not high and will appear in the ultra-low temperature problems such as magnetic and difficult to meet the requirements. From the late seventies, domestic and foreign materials experts vigorously study the manganese-containing low-temperature steel, but in this study
