通过对16MnR钢和两种焊缝的V形缺口Charpy冲击试验的示波曲线特征参数与断口形貌参数的比较分析,提出了反映冲击试件断裂规律的载荷—位移全曲线及其中断的概念,并用这一概念描述了Charpy试件的宏观断裂过程。
By comparing the characteristic parameters of the oscillometric curve and the parameters of the fracture morphology of the Charpy impact test of the V-shaped notch of 16MnR steel and the two kinds of weld, the concept of load-displacement full curve and its interruption reflecting the rupture law of the impact specimen , And use this concept to describe the macroscopic rupture process of Charpy specimen.
