Abstract
This work will study the microstructure and microhardness of a set of ternary Ni-Nb-M (M = Al, Ti, Cr, Fe) alloys, rapidly solidified by copper mold casting. The samples will be manufactured in a vacuum arc furnace in an argon gas atmosphere, using elements of high purity (99.9% Nb and 99.9% Ni) combined with the commercial Ni-alloy Ni-65%Nb donated by CBMM company. These alloys will be b…
