Mo-Si-B alloys have an excellent high-temperature properties due to the formation of intermetallic compounds(IMCs) phases. However, these IMCs phases are too brittle at room temperature(RT). Therefore, many researches for complexation with ductile a-Mo phase have been attempted to overcome this drawback. Considering the characteristic of a-Mo phase, microstructure which has uniformly distributed IMCs phases in continuous a-Mo phase is most ideal. But, common fabrication methods are difficult to control the microstructure. Thus, to enhance the fracture toughness of Mo-Si-B alloys, advanced fabrication method and researches on microstructure control and its Characteristic analysis are required. Especially, effect of size and distribution of IMCs phases on the fracture toughness of Mo-Si-B alloys should be studied.
In this study, Mo-Si-B alloys with IMCs phases of different sizes were fabricated by novel fabrication method. Fracture toughness of Mo-Si-B alloys according to refinement of IMCs phases were investigated at RT.
