Abstract:

Nowadays， the development of metal materials has entered a bottleneck， and a new way of development is urgently needed to break through the current bottleneck. Artificial intelligence gradually emerged in the 1950s， and after more than 60 years of development， AI technology has matured and has been substantially applied in various fields， including the field of materials. The data-driven approach combining data and AI has become a new way to change the development bottleneck of metal materials， which is expected to significantly increase the speed of metal materials research and development. This paper introduces the current situation of alloy design in the field of metal materials. Given that traditional "trial-and-error" methods can no longer meet the requirements of current metal material research and development， it summarizes some applications of machine learning in predicting mechanical properties of metal materials. It also summarizes the shortcomings of machine learning and areas that need optimization， and finally provides prospects for the development of machine learning in the field of metal materials.
