Recent Progress of Chinese Microgravity Materials Science Research and Future Plan

摘要

The field of space materials science research includes material science in space microgravity environment (microgravity material science) and material performance in environments such as high-energy irradiation and atomic oxygen corrosion (materials performance in space environment) two sub-areas. China's space materials science research has gone through more than 30 years since its first satellite-borne experiment in 1987. The research methods range from earlier trial research to purposeful experiment, and will carry out in-depth research in the future. The research conditions also range from earlier simple exploration experiments to systematized and quantitative experiments. The types of materials involved in the study ranged from the single crystal growth of compound semiconductors, the solidification of metal alloys, to the non-equilibrium solidification of functional crystals, colloidal crystals, metal alloys, thin film materials, and nanometers performed in Tiangong No. 1 and No.2 laboratories. China's space research activities have strongly promoted the development of space materials science research.
