Simulation of the Elastic Modulus of Mo Alloys at Both Room and High Temperatures

Abstract:

In this paper, the elastic modulus of a kind of carbide strengthened Mo alloy has been investigated at both room and elevated temperatures. OM image showed that the sintered Mo alloy has an average grain size of ~20 μm. SEM image of the fracture surface of the sintered Mo alloy after tensile deformation to facture showed that intergranular fracture is the dominant mechanism during deformation. A constitutive model has been developed to simulate the elastic modulus of Mo alloys at both room and elevated temperatures. It has been shown that the evolution trend of the elastic modulus predicted by the constitutive model broadly agrees with the experimental counterparts, although most predicted values are slightly higher than the experimental data. The relatively lower experimental data are due to the pores in the Mo alloy, resulted from powder metallurgy fabrication process.
