Abstract

Tungsten based alloys containing up to 40% (preferably 2-40%) of molybdenum are made by mixing the above metals and up to 3% of one or more metals from Group IIIa or IVa of the Periodic Table, fusing the mixture at a temperature above the liquids of all the constituent metals and then cooling to form a homogeneous solid solution of 100% true density. The addition elements may be one or more of Ti, Zr, Th, Hf, Y, the lanthanides or the actinides. The pressure during the fusion stage is preferably no more than 120 microns of mercury. The fusion may be carried out by using the compressed mixture on the electrode in an electric arc struck in vacuum.
