摘要：

In the present paper, the mechanical properties and strengthening mechanism of Nb-based alloy were studied. The scanning electronic microscope, transmission electron microscope, Olympus optical microscope and vacuum hightemperature tensile engine were used to characterize the alloy. The Nb-based super alloy can be strengthening by two approaches. One is solid solution strengthening, i. e. W and Mo in the Nb based alloy act as alloy elements to form solid solution, improving high temperature creep properties. The other one was aging strengthening, i. e. C and Zr were added to form carbide particles during the aging. The effect of C and Zr content and heat treatment on aging strengthening was also investigated. (C) 2011 Published by Elsevier Ltd.
