Structure of a Welded Joint of Directedly Crystallized Metal Based on Ni^sub 3^Al

The structure of a welded joint obtained by argon-arc welding with the use of a composite electrode wire of a Ni^sub 3^Al-base alloy after directed crystallization is studied. It is shown that the use of composite electrode wire containing nanoparticles of tungsten carbide for argon-arc welding prom...

Description
Summary:The structure of a welded joint obtained by argon-arc welding with the use of a composite electrode wire of a Ni^sub 3^Al-base alloy after directed crystallization is studied. It is shown that the use of composite electrode wire containing nanoparticles of tungsten carbide for argon-arc welding promotes formation of a quality weld metal and a defect-free transition zone between the latter and the directedly crystallized alloy based on Ni^sub 3^Al.[PUBLICATION ABSTRACT]
