摘要
在分离式霍普金森压杆(SHPB)装置上,完成了爆炸复合不锈钢复合板(16MnR与0Cr18Ni9Ti)的冲击压缩实验,研究了应变率在350 s-1~1 000 s-1下材料的冲击压缩力学性能。测试结果表明,不锈钢复合板具有应变率强化效应和应变强化效应。金相分析表明,随着应变率的提高晶粒被压缩而细化。
The impact compression experiment of 16MnR+0Cr18Ni9Ti stainless steel clad plate was performed by split Hopkinson pressure bar(SHPB),and the mechanical properties of impact compression of the plate were investigated at strain rates from 350 s-1 to 1 000 s-1.The tested results show that the effects of strain rate and strain strengthening are distinct in the plate.The metallographic analyzed result indicates that the crystal size becomes smaller with stain rate increasing.
