一、前言随着科学技术的发展,各种新型耐高温合金材料的出现,对测定其机械性能,提出了越来越高的要求。尤其是国防工业、化学工业、宇宙空间技术的发展,不仅要求材料具有一定的常温机械性能,而且要求材料在高温状态下,亦应具有一定的抗拉、抗弯强度,冲击韧性等。这台高温真空冲击试验机,就是根据某兄弟单位的特定要求设计的。
I. INTRODUCTION With the development of science and technology, the emergence of various new high-temperature resistant alloy materials has brought about increasingly higher requirements for the determination of their mechanical properties. In particular, the development of the defense industry, chemical industry, and aerospace technology not only requires the material to have certain room-temperature mechanical properties, but also requires the material to have a certain tensile strength, bending strength, impact toughness, etc. at high temperatures. This high temperature vacuum impact tester was designed based on the specific requirements of a brother unit.
