چکیده انگلیسی
Nb-20Si-6Mo (at.%) alloy was prepared by arc melting under Ar-H2 gas mixture atmosphere (Melt Hydrogenation Technology). It indicated that the microstructures of Nb-20Si-6Mo alloy change significantly after the melt hydrogenated treatment. The morphologies of primary Nb5Si3 phase change from polygon to dendrite shapes with the increase of H content. The room temperature compression at same strain rate indicates that the Ïmax decreases with the increase of hydrogen content. High temperature (1400 °C) compression at same strain rate indicates that H addition can cause the peak strain to take place in advance at high deforming temperature. The high temperature compression stress tends to firstly increase and then decrease due to the effect of H addition. The reason for the effects of hydrogenation on the high temperature compression stress of Nb-20Si-6Mo alloy has been discussed.
