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 <5×10−2bar in finely dispersed form. The oxide addition not only improves the hot strength but also greatly improves the ductility.
