Various Properties of Dual-Phase Intermetallic Compound in Ni-Al System

摘要

NiAl possesses the superior oxidation resistant and Ni_3Al shows the good high temperature strength. Various castings with NiAl and Ni_3Al were used in order to investigate the influence of Ni content on the properties. The heats were made by using vacuum induction furnace and its properties were evaluated. This article described the density, hardness, oxidation resistance, corrosion resistance and compression strength of the castings in comparison of other structural materials.
