Thus, it is hard to use Mo-Si series compounds for the components fabrication. Grain refinement is a vital technique which benefits the strength, toughness, and oxidation resistance of Mo-Si-based alloys. A material is brittle if, when subjected to stress, it fractures with little elastic deformation and without significant plastic deformation. Brittle materials absorb relatively little energy prior to fracture, even those of high strength. Breaking is often accompanied by a sharp snapping sound. When used in materials science, it is generally applied to materials that fail wh… the dentist el paso texas
