| 摘 要： | 常温下以不锈钢复合板(16MnR钢板与0Cr18Ni9Ti钢板爆轰复合)和16MnR钢为研究对象,利用分离式霍普金森杆技术,在旋转盘冲击拉伸试验机上完成冲击拉伸加载试验。研究应变率在270～1650s-1范围内,材料的冲击力学特性。测试结果表明,不锈钢复合板和16MnR钢具有应变率强化效应,通过电镜分析确定过载断裂区为韧窝结构,爆轰复合经热处理后材料的塑性基本无改变,两种材料仍为塑性材料。

| Abstract: | The impact tensile behavior of explosive cladding 16MnR/stainless steel plate and 16MnR steel was investigated on Split Hopkinson Tensile Bar.On a rotating disk impact machine,the impact tensile experiments were carried out.The impact characteristics of these materials were studied at strain rate from 270 s-1 to 1 650 s-1.The results show that 16MnR steel and the 16MnR/stainless steel cladding plate are sensitive to strain rate.Dimples are found in the region of fracture by SEM observations,indicating the p... |
