A Method for Testing Dynamic Mechanical Behavior of Materials at Ultra-High Temperature and in-Situ Observation

  • 摘要: 提出了一种新的超高温(1 600 ℃)动态力学性能测试及原位图像获取方法:在原有分离式Hopkinson压杆的基础上,利用加热源为MoSi2的超高温炉实现超高温环境,采用两个活塞组成双同步系统,利用高速摄像机记录动态变形过程。为了验证所提方法的可行性,以TC4钛合金和SiC陶瓷为研究对象,进行超高温动态力学性能测试,其中:在TC4钛合金实验中,应变率为2 000 s-1,温度范围为20~1 400 ℃,测得其流动应力从1.6 GPa降到150 MPa;在SiC实验中,应变率为250 s-1,温度范围为20~1 200 ℃,测得其压缩强度从250 MPa降到220 MPa。根据高速摄像机记录的试样动态变形过程,分析试样的破坏模式,结果表明:在高温空气环境下,TC4钛合金试样表面有氧化层裂开现象,而在氩气环境下则没有;室温下,SiC试样初始裂纹产生时的应力为压缩强度的80%,而在1 200 ℃下为压缩强度的99%。
