Abstract
A method of producing Ti alloys in powder form comprises forming a mixture of Ti oxide with at least one of the metals Al, Sn, Fe, Mn, Mo, Cr, and V, its oxide or chloride; minus 4 mesh (Tyler Standard) particles of Mg in amount at least 100 per cent of the theoretical required to reduce the Ti oxide and alloying addition to at least 90 per cent metal; and Mg Cl2 in amount at least 40 per cent by weight of the Ti oxide plus alloying addition; heating the mixture in an inert atmosphere at not less than 1000 DEG C to effect partial reduction and form an alloy powder having not more than 10 per cent combined oxygen; cooling and crushing the product; leaching with dilute hydrochloric acid; separating out the alloy powder and drying it. In the case especially of TiO2, a second stage reduction is required, the product of the first stage being mixed with minus 4 mesh Ca particles, CaC12, and optionally an alloying addition, and then similarly heated, cooled, crushed, leached and dried. In this stage the Ca should be at least 100 per cent by weight of the Ti oxide in the product, and the CaCl2 from 10 to 150 per cent by weight of the Ti oxide plus alloying addition in the mixture. This second stage treatment is applicable directly to Ti material containing not more than 10 per cent oxygen. Examples of production of alloys of Ti with 1.7 per cent Cr, 1.6 per cent Fe, and 1.3 per cent Mo; with Mn, Mn and Al; with V, V and Al; with Sn, Sn and Al; are given in which oxides of Cr, Mo and V, the chloride of Mn, and metallic Fe, Sn and Al powder are used. Specification 756,999 is referred to.
