固体火箭发动机用钢及其热处理本工艺成果首次提出１８Ｎｉ马氏体时效钢优化的时效新工艺，解决了该钢焊缝脆性问题、创造了旋压、热处理联合成型新工艺方法。对４０６钢材进行了系统研究，提出降低碳含量并对系统工艺参数优化，采用新工艺，防止用该钢制成的发动机壳体低... Solid rocket motor steel and its heat treatment for the first time the results of the proposed 18Ni martensitic aging steel optimized aging process to solve the problem of brittleness of the weld steel, spinning and heat created a new joint molding process. A systematic study of 406 steels has been proposed to reduce carbon content and optimize process parameters of the system with new processes to prevent the engine housing made of this steel from being ...
