Ni_3Al基金属间合金的研究进展

Research Progress of Ni_3Al-based Intermetallic Alloys

介绍了Ni3Al基金属间合金研究的现状和前景。Ni3Al具有高熔点、低密度和良好的抗氧化性,但是在室温下塑性差和高温时强度低限制了其作为工程材料的应用,通过对Ni3Al基金属间化合物的合金化制备及力学性能的研究,以期改善Ni3Al基金属间合金的室温塑性和高温强度。

This paper reviews the high mehing temperature, low density and low strength at high temperature, and mechanical properties. progress in current research on Ni3Al-based and good resistant to oxidation etc. However which limits its use as engineering materials intermetallie alloys. Ni3Al have properties such as its properties of low ductility at room temperature are improved by studying its alloying, preparation and mechanical properties.
