The microstructure and mechanical properties of a copper bearing agehardeningsteel were studied.
研究了含铜时效钢焊接热影响区的组织与性能。

The new domestic - developed plastic mould steels include prehardening steel . agehardeningsteel, quenching-tempering steel, cold -forming steel, and anti - corrosion steel, etc.
国产新型塑料模具钢主要有预硬钢、时效硬化钢、淬火——回火钢、冷挤压成型模具钢、耐蚀钢等类型。

The results showed that as the content of Ti increasing , fine precipitates distribute dipersely, grain fine and age - hardening enhanced in the steel, so tensile strength in this steel is improved.
