Abstract

1,142,683. Alloys; powder metallurgy. IIT RESEARCH INSTITUTE. Feb.24, 1966 [Feb. 26, 1965; Jan. 3, 1966 (6)], No. 8184/66. Headings C7A and C7D. A solid alloy having an ultrafine micro-structure is produced by (a) preparing an alloy powder consisting by weight of 0À6 - 4%C, at least 15% of one or more of Cr, W, Mo, Ti, Ta, Nb, Zr, Hf, V and Al, the balance being at least 30% of one or more of Co, Fe and Ni, by mechanically crushing the alloy or atomizing the molten alloy, (b) sealing the powder within a metal jacket and heating to a hot-working temperature, and (c) compressing and mechanically hot-working the jacketed powder to produce a body of consolidated powder having a uniformly dispersed hard phase with a grain size of 0À5 - 3 microns. In a modification particularly for use as a cutting tool, a blend of two powders is used, one powder to form a matrix and the other to form a relatively harder and wear-resistant dispersal constituent. Specifically, powder may be pressed at 5 - 30 t. s. i. in Mo-lined cans, heated to forging temperature (1850‹ - 2150‹F.), forged, hot-rolled, annealed (1500‹-1600‹F.), machined to shape, austenitized (2100‹-2200‹F. oil or air cooled, and tempered one or more times at 950‹- 1100‹F. Many compositional examples are given of alloys.
