Abstract
A process for manufacturing a component with a base of Co—Cr—Mo alloys having values of average ultimate elongation at 800° C. greater than 10% and of average yielding load at 800° C. greater than 400 MPa, comprising: obtaining a sintered component by additive sintering of powders of Co—Cr—Mo alloys containing carbides irregularly dispersed in the molten matrix; Conducting a first heat treatment on the sintered component for solubilization of the carbides at a temperature of between 1100° C. and 1300° C. for at least 2 hours to form a solubilization intermediate; and cooling the solubilization intermediate at a cooling rate at least equal to that of cooling in air to form a cooled intermediate; and conducting a second heat treatment on the cooled intermediate at a temperature of between 700° C. and 1000° C.
