摘要

摘要: 借助纳米力学测试系统测试了4 GPa压力处理前、后7075铝合金的硬度、弹性模量和塑性变形量，并结合对其显微组织的观察，探讨了高压处理对7075铝合金微观力学性能的影响。结果表明：4 GPa压力处理能增大7075铝合金的硬度和弹性模量，减小塑性变形量，有效地提高了合金抵抗变形的能力。

Abstract: The hardness, elastic modulus and plastic deformation of the 7075 aluminum alloy before and after 4 GPa pressure treatment are measured by nano-indenter, and combined with the observation for the microstructure. The effects of high pressure treatment on micro-mechanical properties of 7075 aluminum alloy are investigated. The results show that 4 GPa pressure treatment can increase the hardness and elastic modulus of the 7075 aluminum alloy, and decrease its plastic deformation. As a result, the non-deformability of the alloy is improved effectively.
