摘要
利用压剪试样 ,采用Hopkinson压杆试验技术 ,研究了船用 90 7A钢在应变率 γ 2 .0 × 1 0 5s-1的条件下的绝热剪切行为 ,结果表明压剪试样韧带的变形是一个两端向中间传播的剪切变形过程 ;在该应变率条件下 ,该钢的绝热剪切带属于相变剪切带 .
The adiabatic shear behavior of 907A steel with shear strain rate of 2.0×10 5 s -1 was investigated by using split Hopkinson bar and hat-shaped specimen. The results show that the deformation of the specimen ligament is a shearing procession spreading from both ends to the center part of the shear band, and at this rate, the phase transformation takes place in the adiabatic shear bands of the steel.
