However, a temper brittleness has appeared after high temper. 空冷后高温回火产生回火脆性。
Analysis and Forecast of High temper Weather of Zhumadian 驻马店市高温天气分析与预报
The effect of high temperature temper brittleness on the microstructure and mechanical properties of carbonic steel was studied. 研究了碳素结构钢的高温回火脆性及其对显微组织和有关性能的影响;
Compared the welding residual stress with testing data, the both accord each other, and high temperature temper reduce the peak value of welding residual stress effectively. 将计算得到的残余应力分布与实测的残余应力数据进行比较,两者符合较好,而且高温回火有效的降低了焊接残余应力的峰值。
The microstructure of high speed steel cold rolls, after processed by half-hardening of low temperature quenching and high temperature temper, was analyzed by optical microscopy, scanning and transmission electron microscope, and the mechanism was analyzed. 利用光学显微镜、扫描及透射电子显微镜,对高速钢冷轧辊经低淬、高回的半硬化处理后的组织进行了分析,探讨了其性能优良的内在机理。
