METHOD OF MAKING ANNULAR WORKPIECES FROM HOT-ROLLED NICKEL ALLOY SHAPES Russian patent published in 1994 - IPC

Abstract RU 2013175 C1

FIELD: metal working. SUBSTANCE: rods of measured length are cut, bent into a ring, butt-welded, calibrated by diameter, and thermally processed. Welded annular workpieces from shapes of aged nickel alloys are then subjected to hot rolling at conditions close to isothermal to at least 10% . EFFECT: enhanced efficiency of the method. 5 cl, 3 tbl, 4 dwg
