摘要:对16MnR和Q235两种钢材进行了多组试样的小冲杆试验,研究了材料微观缺陷对其小冲杆试验结果的影响。结果表明:由于Q235钢微观缺陷相对较多,其小冲杆试验的载荷-位移曲线分散度较大,试样断口形貌也较粗糙;材料微观缺陷对小冲杆试验的抗拉强度有比较明显的影响,而对屈服强度没有影响。
16MnR and Q235 steels were used to carry out small punch test with multi-group samples, in order to study the effects of material microdefects on the test results. The results show that Q235 steel had more microdefects, larger dispersivity in load-displacement curves and rougher fracture morphology. The microdefects had obvious effect on the tensile strength of the small punch test and no effect on the yield strength.
