    摘要:

    鈮硅基復合材料具有優(yōu)異的高溫強度和抗蠕變性能,是高推重比航空發(fā)動機高壓渦輪葉片和導向葉片極具潛力的候選材料,被認為是最有開發(fā)應用前景的下一代超高溫結構材料。本文主要論述了對Nb-Si系原位復合材料的研究近況,主要是總結通過合金化和制備工藝的改善,以期使室溫斷裂韌性、高溫強度及抗氧化性能獲得良好匹配,對進一步提出優(yōu)化的制備和研究方案奠定了基礎。

    Abstract:

    The ultrahigh-temperature Nb-Silicide-based composites have been extensively studies as candidate materials for the high-pressure turbine blade and oriented blade of the high thrust-weight ratio aero-engine due to its attractive mechanical and physical properties. This essay talks about the research status of the ultrahigh-temperature Nb-Silicide-based composites. The main research of multiphase refractory Nb–Si in situ composite is to make room temperature fracture toughness, high elevated-temperature strength and resistance to oxidation to have a better match through alloying and the improvement of preparation technology. And hoping to lay a basis for further research.
