摘要：
Three Mo-Ti-Si-B alloys with compositions of 50Mo-20Ti-20Si-10B, 40Mo-30Ti-20Si-10B and 30Mo-40Ti-20Si-10B (at.%) were designed and prepared by arc-melting. Microstructure evolution at 1600 degrees C and oxidation mechanism at 800 degrees C of these alloys were analyzed. 50Mo-20Ti-20Si-10B suffered from pesting because of a large volume fraction of Mo3Si, which produced porous products with severe volume expansion. Both 40Mo-30Ti-20Si-10B and 30Mo-40Ti-20Si-10B have better oxidation resistance. It can be inferred that during long-term oxidation, interactions between constituent phases contributed to the overall oxidation resistance of the alloys.
