The effect of carbide solvation on the γ/γ+δ boundary temperature Tδ and the equilibrium relationship between the alloying elements at the γ/γy +δ boundary in austenitic steels at high temperature have been studied, and the variation of the ferrite volume fraction with temperature in α+ γ dual phase steel has been investigated. The relative expressions are derived from many experimental results, which provides a basis for quantitative calculation, composition design, determination of the working processes,and prediction of the mechanical properties and the structure of the austenitic steels.

This paper briefiy introduces the R&D of intermetallics in China. R&D on intermetallics in a national scale in China began near ten years ago. The investigation in past years focused on the fundamental research and materials development. A significant progress has been made. Various components that made of Ti3Al Ni3Al, TiAl and Fe3Al have been successfully manufactured Some of them have been evaluted. It is expected that some intermetallic alloys will be produced in an industrial scale in the near future.
