The wear behavior of strongly ordered intermetallic compounds which have been modified by introduction of a ductile phase will be studied. The effects of volume fraction, size and spacing of the ductile phase on the deformation mechanisms and wear resistance of Ni-Al-Fe and Ni-Si systems will be studied. Wear behavior will be compared with fracture toughness data obtained at several different rates of loading and evaluated in terms of deformation mechanisms. The effects of environment will be evaluated also to assess the extent of oxidative wear.

强有序金属间化合物的磨损行为 其通过引入延展相而被改性， 被研究。 研究了颗粒体积分数、粒径和间距对颗粒粒径分布的影响 韧性相对变形机制和磨损的影响 研究了Ni-Al-Fe和Ni-Si系的电阻。 磨损 行为将与获得的断裂韧性数据进行比较 在几种不同的加载速率下， 变形机制 环境的影响将是 还评估了氧化磨损的程度。
