Joining of molybdenum and its application

摘要: In this work fusion and solid state welding techniques for joining PM refractory metals are adressed. The weldability is discussed evaluated by electron beam friction experiments. EB-welding experiments were performed on rolled sheets made of different Mo-based materials. While a significant decrease in the mechanical properties was found weldments unalloyed molybedenum alloy TZM, good given Mo41Re. A procedure established used manufacturing thin walled tubes. Rotary carried out rod material Mo-alloys TZM MHC. Suitable process parameter determined successfully transferred tubular parts.
