| 摘 要： | The effects of Cr,Al and B addition on the microstructure and high-temperature oxidation behaviors(at 1200,1250 and 1300℃) of Nb-Ti-Si based alloys were investigated.The results showed that the addition of Cr stabilized α-Nb5 Si3,while Al promoted the formation of β-Nb5 Si3 and adding B promoted the formation of γ-Nb5 Si3.Among the three elements,Al and Cr were beneficial to oxidation resistance at 1200℃,and B was favorable to the...
