Alloys based on refractory metal silicides have been considered as potential candidate materials that can be equipped with a temperature capability superior to Ni based superalloys. While alloys based on the Nb-Si and Mo-Si-B systems, as well as TiC doped Mo-Si-B alloys (referred as MoSiBTiC alloys) have been shown to exhibit some attractive material performance in terms of room temperature toughness, high temperature strength, and oxidation resistance, there are still some challenges that have to be overcome to satisfy these conflicting property requirements. In this talk, our recent development on the Nb-Si alloys and MoSiBTiC alloys will be reviewed. We will also discuss the room temperature deformation capability of the monolithic silicides, which is examined by nano-mechanical testing.
