摘　　要：研究了 H1 3锻材过热的宏观断口、显微组织及其成因。研究结果表明 ,锻材断口呈石状、显微组织枝晶特粗大的原因主要是由于锻造加热工艺控制不当造成。而一般过热的锻材可通过高温快冷正火处理来改善其显微组织 ,从而获得 NADCA( ASTM)标准的合格级别组织。This article has analyzed the macroscopic fracture, microstructure of the overheat H13 forging and its reason. The result shows that due to the reason of unsuitable control of the forging process ,the forging fracture is in stone shape and the microstructure is extremely rough. Generally the microstructure of the overheated forging can be improved by means of high temperature fast cooling normalizing so that the qualified level from NADCA and ASTM standards can be obtained.
