METHOD FOR PRODUCTION OF BILLETS FROM POWDERS OF TITANIUM ALLOYS Russian patent published in 1994 - IPC

Abstract SU 1589490 A3

FIELD: powder metallurgy. SUBSTANCE: method consists in coating of titanium powder with clad layer of alloying component to form film of intermetalic phase, molding of clad powder and subsequent sintering of molded material. Sintering is carried out at temperature higher than powder surface film melt point by 15-30 C for 0.5-1 h. Heating is effected within temperature range of 20-800 C at rate of 5-10 deg. /min, and from 600 C to sintering point at rate of 15-20 deg/min. EFFECT: improved mechanical properties of products. 2 tbl
