The microstructure and mechanical properties of materials produced by wide gap brazing (WGB) and laser beam (LBW) cladding with different blends of Mar M247 and Amdry DF-3 brazing powders were studied. It was shown that LBW Mar M247-based materials comprised of 0.6 to 1 wt % B were weldable. The weld properties were superior to WGB deposits with the same bulk chemical composition, due to the formation of a dendritic structure typical for welded joints, and the precipitation of cuboidal borides of Cr, Mo, and W in the ductile Ni–Cr based matrix. Both materials were found to have useful properties for three-dimensional (3D) additive manufacturing (AM) and repair components manufactured from high gamma prime precipitation hardened superalloys.
