METHOD FOR PRODUCING CHROME-BASE ALLOY FOR MAKING FORGING TOOLS Russian patent published in 2002 - IPC

FIELD: metallurgy, namely production of alloys for making tools for plastic working of materials, possibly in metal working industry branches for hot isothermal forging of fire resistant alloys. SUBSTANCE: method comprises steps of hot isostatic compaction and homogenization of billet; before hot isostatic compaction burdening initial material for making raw billet of alloyed powder mixture; sintering raw billet in temperature range 1600-1750^°C for 4-10 h; using raw billet with relation of its height to diameter or to diagonal equal to 0.4-1.0. EFFECT: reduced loss of yield, uniformity of billet structure in cross section. 2 cl, 1 tbl, 1 ex
