ABSTRACT:
The workability of a Group VIA metal, such as molybdenum, or an alloy of a Group VIA metal is improved by heat treating the Group VIA metal or alloy of the Group VIA metal in an environment for causing particles to be formed in the Group VIA metal or alloy of the Group VIA metal, and cooling the Group VIA metal or alloy of the Group VIA metal at a rate sufficiently rapid to prevent formation of particles large enough to cause embrittlement thereof. A ductile, recrystallized molybdenum or alloy thereof may thereby be produced.
