Abstract

PURPOSE:To make the dispersion of Cr particles unnecessary in a hard Ni alloy without deteriorating the hardness and corrosion resistance by regulating the Cr and Al contents and adding a proper amount of Fe and a very small amount of Ti. CONSTITUTION:This hard alloy consists of, by weight, 18-48% Cr, >10-30% Fe, 2.5-4.5% Al and the balance Ni or further contains 0.1-1% Ti and has >=500 Vickers hardness. Dispersed Cr particles having >=1mum particle size are not contained in the alloy. When the Cr, Fe, Al and Ti contents of the alloy are represented by a%, b%, c% and d%, respectively, the composition is preferably regulated so as to satisfy 60-0.25b>=a+4.5(c+d)>=48-0.06b. By this composition a hard alloy having high strength after aging, contg. no dispersed Cr particles and showing superior decorativeness and corrosion resistance is obtd.
