The microstructure of gas tungsten arc welds of a (Ni,Fe)/sub 3/ (V,Ti) long-range-ordered alloy has been investigated. Crack-free welds were produced in which the heat affected zone and fusion zone were disordered and softened. A post-weld heat treatment increased the hardness of both zones by reordering the structure. The reordering treatment produced additional hardening in the fusion zone due to precipitation of small VC particles on grain boundaries and matrix dislocations.
