Abstract
A composite sintered material of a mixed-phase structure comprising fine particles of hard compound compactly and uniformly dispersed in grains of matrix of titanium or titanium alloy. The material is outstanding in abrasion resistance, strength, toughness, etc., and also has high resistance to corrosion by molten nonferrous metals and is therefore reduced in the likelihood of dissolving out into the melt. The sintered material is produced by uniformly mixing together a metal powder for forming the matrix of the desired sintered material and a powder for forming particles of hard compound to be dispersed, molding the powder mixture into a block under pressure, atomizing the block while melting the block and sintering the resulting powder.
