摘要
通过分析,发现试样的加工是造成300M高强钢脱碳试样硬度值异常的主要原因。本文采用不同的加工方法对试样进行处理,逐一分析了线切割、车床、磨床加工后硬度的变化。根据研究结果,制定了合理的试样加工规范,取得了良好的效果。
Through analyzing,it is found that the processing of the sample is the main reason for the abnormal hardness of 300M high strength steel decarbonized sample.In this paper,different machining methods have been used to treat the samples,and the hardness changes after wire cutting,turning on the lathe and grinding on the grinder have been analyzed one by one.According to the research results,a reasonable sample processing specification has been established,and good results have been obtained.
