The Laboratory of Space Materials Science and Technology was founded in 1993. Its main research objective is to carry out ground simulation of space environment characterized by microgravity,containerlessstate and ultrahigh vacuum, and on this basis, to investigate the microstructures, physical and chemical properties, phase transformation, preparation, and processing of various materials.

GroundSimulationResearch of Space Environment
Electromagnetic levitation, acoustic levitation and drop tube techniques are applied to balance gravity and produce containerless state under ground conditions. Ultrahigh vacuum technique is also applied to simulate space environment. Research emphasis is put on the kinematics and dynamics of containerless processing.
Thermophysical Properties and Materials Processing in Space Environment
Environmental condition shows the most significant influences on the liquid state and liquid to solid phase transformation. The research projects include: the achievement of undercooled and hypercooled states of melts, the measurement of thermophysical properties of metastable liquids at containerless state, and the investigations on rapid solidification of single phase and polyphase materials.
Development of Advanced Materials Under Space Simulation Conditions
The related research projects are: the development of rapidly solidified high purity metallic materials, the production and exploitation of bulk metallic glasses and the containerless processing of energy materials.
Computational Materials Science Research for Space Environment
The methods of computational materials science, such as MD, MC, PFA, and VR, are applied to optimize materials design, improve production technology and reduce manufacture cost for materials science in space.
A total of more than 200 scientific papers have been published, in which more than 150 are indexed by SCI. The research results of acoustic levitation were reviewed in Nature and Science for 3 times. The scientific achievements have won important official awards.
In the last two decades, more than seventy scientists from over ten countries have been invited to Xi’an for academic visits and mutual exchanges.
Professor W. Kurz of Swiss Federal Institute of Technology at Lausanne won the National Friendship Award and Sanqin Friend Award in 2003 for his long lasting cooperation with this laboratory.
