抄録

NiAl binary and Ni-Fe-Al ternary alloys, with the composition of 40.50at%Al and x ;[Fe]/( [Nil+Fe])=0-0.20, were fabricated by the reactive hot-press sintering. The addition of Fe to NiAl resulted in the decrease of fracture toughness in the case of 50at%AI, however, toughness of 40 and 45at%Al alloys increased to about 30% of the value of NiAl.<BR>NiAl and Ni-Fe-45at%Al matrix composites were fabricated successfully. When the proportionality limit of matrices were <500MPa, it increased by the addition of A1₂O₃ short fibers. In the Ni-Fe-45at%Al matrix composites reinforced by β-SiC whisker, the proportionality limit markedly increased with the addition of under 5vol%. The Al₂O₃ short fiber and the β-SiC whisker reinforced Ni-Fe-45at%Al matrix composites had higher strength at room temperature than the NiAl matrix ones.
