摘要
对我国自行设计的专利产品G50钢的动态力学性能进行了实验研究。实验结果表明:G50钢是应变率不敏感材料,其动态压缩时会产生45°剪切破坏。金相细观分析表明,G50钢的应变率不敏感性是由其细观结构所决定的,材料的45°剪切破坏则是由于其热塑失稳、绝热剪切造成的。
The dynamic mechanical behaviors of a Chinese patent G50 steel were studied. Test results show that G50 steel is insensible of the strain rate, and dynamic compression leads to shear failure with the angle of 45° . Metallographic analyses indicate that the 45° shear failure results from thermal plastic instability and adiabatic sheafing.
