通过SA515Gr.70钢的不同温度正火和13MnNiMoNbR钢正火后不同温度回火试样的示波冲击试验,研究了不同热处理工艺对冲击曲线的影响.
The influence of different heat treatment process on the impact curve was studied by means of the oscillometric impact test of normal temperature of SA515Gr.70 steel and tempered samples of different temperature after normalizing of 13MnNiMoNbR steel.
