用超高强度钢制造固体火箭发动机壳体是材料工程课题之一。根据发动机壳体对超高强度钢的各项要求选择钢种,针对薄壳体的具体情况确定控制意外断裂的主要因素,实施一套易于为制造工厂掌握的检验方法及控制壳体韧性的非标准检测方法。同时,对各项新工艺过程之间的合理衔接问题,经济效益以及资源合理利用等问题都需全面考虑,方
The manufacture of solid rocket motor housings with ultra-high strength steel is one of the material engineering topics. According to the requirements of the engine casing for ultra-high strength steel, the steel grades are selected, the main factors controlling the unexpected breakage are determined according to the specific circumstances of the thin shell, and a set of inspection methods and control of the toughness of the shell Standard test method. At the same time, issues such as the issue of reasonable cohesion between various new technological processes, economic benefits and rational utilization of resources must be fully considered.
