| 摘 要： | 在断裂冲击试验机上,用CT试样测定了35CrMnSiA、PCrN_(i1) M_0与45号钢的动态断裂韧性K_(1D),并与静态下的K_(1C)作了比较。K_(1D)一般比K_(1C)值低。本试验用瞬志波形存贮器寄存波形信号,用微机自动进行数据处理,并打印结果及绘制P—t曲线。

| Abstract: | Dymanic fracture toughness K_(ID) was measured for 35CrMnSiA, PCrNiMo and No. 45 steel with CT-Specimen on a fracture testing mechine Testing results were compared with stat-ic K_C and K_(ID) was shown lower than K_(IC) in general. A transient memorizer was used to store wave form signals and a microcomputer is used to conduct data processing, results printing and curve plotting for higher efficiency and accuracy. |
