SOLID ALLOY (VARIANTS) AND METHOD OF PREPARING THEREOF Russian patent published in 1999 - IPC

FIELD: manufacture of multipurpose cutting tools, polishing powders and measuring instruments. SUBSTANCE: high-melting titanium compound-based solid alloy comprises as high-melting titanium compound, titanium carbonitride composed of TiC_xN_y wherein 0,45 ≤ x ≤ 0,98, 0,02 ≤ y ≤ 0,55 and x+y=1, and metallic bond comprises nickel and molybdenum at Ni/Mo=1/6 ratio in amount of 9-12 vol % based on total amount. Solid alloy comprises, as high-melting titanium compound, titanium oxycarbonitride composed of TiC_xN_yO_z wherein , and x+y+z= 1, and metal bond comprises nickel and molybdenum at Ni/No=1/6 ratio in amount of 9-12 vol % based on total amount. Solid alloy comprises, as high- melting titanium compound, titanium oxycarbonitride composed of Ti_1-mMe_mC_xN_yO_z, wherein Me is Zr or V; and x+y+z=1, and metal bond comprises nickel and molybdenum at Ni/Mo 1/6 ratio in amount of 9-12 vol % based on total amount. Powder-like carbonitride or oxycarbonitride or alloyed oxycarbonitride is mixed with metallic nickel and molybdenum powders. The resulting mixture is subjected to grinding to dispersity of 2-3 μk. Mixture is then briquetted and sintered. Sintering is carried out at heating and cooling rate of 16-18°/min at pressure of (2-5)•10^-1 mm Hg. EFFECT: high physico-mechanical properties and improved wear resistance of multipurpose solid alloy. 5 cl, 6 ex
