Recent developments in high temperature intermetallics research in China

A comprehensive survey was made of various advances of intermetallics research in China. The investigation focussed on the fundamental research and materials development. Charge density distribution and site occupancy of alloying elements, environmental embrittlement and chemical reaction, interface structures and phase transformation at the atomic scale, nanocrystalline intermetallics and its thermal stability, superplastic behavior and anomalous yield strength peak are reviewed. Several Ti–Al and Ni–Al based alloys have been manufactured, and show good mechanical properties. Diverse components have been fabricated successfully.
