Microstructures and Mechanical Property of MoSi2/TSi2(T=Cr,V,Nb,Ta,Ti)Two-Phase Alloys

Keywords： Phase stability

In order to improve the low temperature ductility and high temperature strength ofMoSi2 while keeping its superior high temperature oxidation resistance, the present work attempts to combine MoSi2with the C40 type disilicides of transition metals including Cr, V, Nb, Ta and Ti. The possibility of producing a thermally compatible composite of MoSi2 and the C40 disilicides is discussed by critical assessment of MoSi2-TSi2(T=Cr, V,Nb,Ta, Ti) pseudo-binary phase diagrams. Relative phase stability between the CIIb MoSi2 and the C40 TSi2 is investigated and lamellar MoSi2/TSi2 two-phase microstructures are obtained by appropriate choice of composition and heat-treament. Preliminary result on the microhardness of MoSi2/TSi2two-phase alloys is also discussed.
