低碳高强钢热处理后的组织和力学性能
Microstructure and Mechanical Properties of Low Carbon High Strength Steel after Heat Treatment
摘要
Abstract
Microstructure and mechanical properties of low carbon high strength steel at different quenching and tempering temperatures were studied.The results show with the increase of quenching temperature,the strength and impact energy increase first and then decrease;with the increase of the tempering temperature,the strength decreases,while the impact energy increases gradually.When the quenching temperature is 900 ℃ and the tempering temperature is about 500 ℃,the tempered troostites are fine and compact,the carbide distributes uniformly,and therefore the comprehensive mechanical properties of the steel are better.关键词
