摘要
本文研究用山形缺口试样测量30CrMnSiNi2A钢和Al-7Si-0.45Mg铸造合金的断裂韧性,与标准测量方法测量的断裂韧性值进行比较,分析山形缺口试样测试的结果与标准断裂韧性试样测量结果差异的原因。
Fracture Toughness has been determined on the high strengthsteel30CrMnSiNi2A and the casting alloy Al-7Si-0. 45Mg by meansof the Cherven-notched specimens. The results have been compared with those by the ASTM E399-81 standard and furtherdiscussed.
