摘要
大规格高碳钢线材轧后自然放置一段时间,其力学性能发生较大变化,尤其是线材的面缩率和伸长率提高幅度较大,通过对13mm82B线材进行不同时间段残余应力及气体氢含量的测定分析,初步探明了时效前后力学性能变化的原因及规律。
After some time of natural placement after rolling, the mechanical properties of largesize highcarbon steel wire rods change greatly, especially the reduction ratio of area and the extensibility increase greatly Through measuring and analyzing residual stress and gas hydrogen content of 13mm 82B wire rods at different time internals, the reason and the rule of the change of mechanical properties are preliminarily verified before and after aging
