  • 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.
