【 摘 要 】

Magnesium alloys combine several favorable attributes, including low density, high strength-to-weight ratio, good damping capability and so on. However, their application is limited by their relatively poor high-temperature performance and creep resistance. These deficiencies can be alleviated by the alloying-induced solid solution and precipitation strengthening. The integrated computational materials engineering (ICME) approach based on the calculation of phase diagram (CALPHAD) software is shown to accurately quantify the effect of alloying elements on the strengthening precipitates. Thus, it is quite instrumental forin enhancing the alloy development process, alloy design, and manufacturing optimization. This paper summarizes the theoretical background of CALPHAD-based ICME, outlines the current research progress in this direction and provides some insights into future development.
