摘要：

通过人工预变形和时效的方法对热轧H型钢进行了应变时效处理。研究了应变时效对热轧H型钢低周疲劳寿命、循环应力响应和循环韧度的影响。研究结果表明，热轧H型钢和应变时效H型钢都表现出了良好的循环特性，都是以循环稳定为主的疲劳循环；热轧H型钢和应变时效H型钢都具有较好的高应变低周疲劳韧度，且应变时效对H型钢的低周疲劳循环韧度的影响较小。

Through the method of artificial pre-deformation and aging,the strain aging treatment on hot rolled H-shaped steel was done. The effects of strain aging on low cycle fatigue life, cyclic stress response and cyclic toughness of hot rolled H -shaped steel were studied. The results show that hot rolled H-shaped steel and strain aging H-shaped steel both show excellent cycle characteristics,which are all the fatigue cycle with cycle-stability-based; hot rolled H-shaped steel and strain aging H-shaped steel both have good low cycle fatigue toughness, and strain aging H-shaped steel has less influence on low cycle fatigue toughness of H steel.
