Ferrovanadium carbide addition agents comprising 75 to 85% vanadium, 8 to 12% carbon, 8 to 12% iron, less than 2% oxygen and having a density of from about 5.8 to about 6.2. The addition agents are produced by fusing vanadium oxide, iron and carbon at about 1700.degree. C. to about 2100.degree. C.

Ferrovanadium carbide addition agents and process for their production

A process is provided for the aluminothermic production of low nitrogen containing chromium and chromium alloys, said chromium alloys comprising about 80% chromium, about 20% nickel and less than 0.005% nitrogen, said alloys being especially desirable for use as master alloys in production of super alloys where levels of nitrogen imparted by chromium alloying elements are critical.

Process for aluminothermic production of chromium and chromium alloys

This invention relates to molybdenum-titanium-zirconium aluminum master alloys containing about 20 to 25% molybdenum, about 1 to 5% titanium, about 40 to 50% zirconium, balance aluminum and not more than about 0.004% nitrogen.

Molybdenum-titanium-zirconium-aluminum master alloys

This invention relates to molybdenum-titanium-zirconium-aluminum master alloys containing about 35 to 40 molybdenum, about 1 to 5% titanium, about 15 to 25% zirconium, balance aluminum and not more than about 0.004% nitrogen.

The invention relates to master alloys containing about 55 to about 70% tungsten, about 2 to about 10% titanium, balance substantially aluminum.

Tungsten-titanium-aluminum master alloy

Carbide addition agents comprising (a) from about 20 to about 60 atomic percent of carbon, (b) from about 25 to about 60 atomic percent of at least one metal selected from the group consisting of vanadium and columbium, and (c) from about 10 to about 40 atomic percent of at least one metal selected from the group consisting of iron and manganese, are useful alloy addition agents for steel.
