Effect of High Pressure Heat Treatment on Microstructures and Micro-mechanical Properties of CuZn Alloy

摘要

The hardness, elastic modulus, and friction coefficient of the CuZn alloy before and after treatment at 700 °C and 3 GPa for 10 mins were measured by nanoin-denter. Effects of high pressure heat treatment on its mi-crostructure and micro-mechanical properties were discussed. The results show that high pressure heat treatment can refine the microstructures of the CuZn alloy, and its hardness, elastic modulus, ratio of hardness, and elastic recovery rate after the 3 GPa treatment increased by 15.44, 4.89, 8.82 and 35.90, respectively. And the friction coefficient is also decreased.
