Abstract
A method for powder metallurgical production of a high temperature alloy body consists of mixing powdered alloy components or pre-alloys in the desired proportions; cold working the mix under a protective atmosphere; canning the cold-worked powder mixture; compressing the canned powder by extrusion or hot isostatic pressing to a form of dense blank; cutting said blank into slices; forging them at a constant temperature within the range of from 0.6 to 0.75 of the melting point at a strain rate of from 10.sup.-3 to 10.sup.0 S.sup.-1 ; and thereafter subjecting the forged body to a coarse-grain annealing between 1230.degree. and 1300.degree. C for up to 3 hours.
