A relatively small number of elements—titanium, zirconium, hafnium, niobium, and vanadium—are used for alloying molybdenum (they are introduced in amounts of 0.1–1.5 percent). Such amounts provide high heat-resistance and sufficient plasticity (rhenium and tungsten may be introduced in amounts up to 50 percent, with retention of satisfactory deformability of the alloy). The heat resistance of molybdenum alloys increases with additional alloying with carbon (up to 0.4 percent), which leads to the formation of clearly heterophase alloys with carbide hardening. Small quantities of boron, chromium, nickel, tantalum, and a number of rare earths are also used to improve the technological properties of molybdenum alloys.
