摘要 Nb-Si-Cr基超高温合金作为一种新型的超高温结构材料,具有良好的高温强度、适中的室温断裂韧性以及良好的高温抗氧化性,而成为近年来研究的热点。阐述了合金化元素对Nb-Si-Cr基超高温合金对其组织、晶型结构和凝固路径的影响,并对Nb-Si-Cr基超高温合金的发展趋势进行了分析。 Nb-Si-Cr based ultrahigh temperature alloys were studied as a kind of high temperature structural materials in terms of high temperature strength, moderate room temperature fracture toughness and excellence oxidation resistance. The effects of alloying elements on the microstrueture, crystal structure and solidification path was illustrated, and the trend in the development of Nb-Si-Cr based ultrahigh temperature alloy was put forward.
