我国各重机厂在金相检验及铸锻件解剖方面做了大量的检验和科研工作,这对于判断和确定大型铸锻件的质量和制造工艺是否合理、分析缺陷产生的原因、提出改进工艺的意见、提高铸锻件的质量起了很大的作用。根据重机行业第三届金相专业会议的建议,将各重机厂多来年在金相检验及铸锻件解剖方面所做的一系列可喜的成果汇集起来,陆续以金相专辑的形式在本刊发表,以便于互相学习和借鉴。本期是金相专辑的第一集。
China’s heavy machinery plant in the metallographic examination and casting forgings anatomy has done a lot of inspection and research work, which is to determine and determine the quality of large forgings and manufacturing process is reasonable, analyze the causes of defects, put forward the views of improving the process , Improve the quality of castings and forgings played a significant role. According to the third session of metallurgical industry heavy machinery industry recommendations, the heavy machinery plant in the coming year in the metallurgical test and casting forgings anatomy made a series of gratifying results together, one after another in the form of metallographic album in this Publication, in order to learn from each other and learn from. This issue is the first album of the album.
