The Effect of Ductile Phases on the Deformation and Wear of Brittle Intermetallics

对引入延性相改性的强有序金属间化合物的磨损行为进行了研究。研究了塑性相的体积分数、尺寸和间距对Ni-Al-Fe和Ni-Si体系的变形机理和耐磨性的影响。磨损行为将与在几种不同加载速率下获得的断裂韧性数据进行比较，并根据变形机制进行评估。还将评估环境的影响，以评估氧化磨损的程度。

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.
