Outline of Final Research Achievements

We have proposed a coating system with a duplex layer structure containing a Re-based alloy phase. Using Re-based alloys fabricated by tetra-arc furnace, the tie-line compositions of each phase in a Re-Nb-Al, Re-Nb-Si, and Re-Si-Al systems were experimentally determined.
