Abstract: A Mo—Si—B alloy has a matrix of Mo or a Mo solid solution, wherein 25% by volume to 90% by volume of molybdenum silicide and molybdenum boron silicide, optionally together with molybdenum boride, are incorporated. The alloy also contains 0.1-5% by volume of one or more oxides or mixed oxides with a vapor pressure at 1500° C. of

Abstract: Semi-finished or finished parts are made from a molybdenum alloy with intermetallic phases, preferably molybdenum-silicide, molybdenum-boron-silicide, optionally also molybdenum-boride phases. Starting from mechanically alloyed powder, hot compacted material exhibits superplastic forming behavior. It is thus possible to lower the forming temperature by at least 300° C., thus permitting processing on conventional plants.
