Abstract
Molybdenum alloys are provided with enhanced oxidation resistance. The alloys are prepared by the addition of silicon and boron in amounts defined by the area of a ternary system phase diagram bounded by the points Mo-1.0% Si-0.5% B, Mo-1.0% Si-4.0% B, Mo-4.5% Si-0.5% B, and Mo-4.5% Si-4.0 B. The resultant alloys have mechanical properties similar to other high temperature molybdenum alloys while possessing a greatly enhanced resistance to oxidation at high temperature. The alloys are composed of a matrix of body centered cubic molybdenum surrounding discrete intermetallic phases. A variety of alloying elements are added to the base composition to modify the alloy properties.
