Methods of improving the working capacity of metal alloys

摘要

A method of processing an alloy workpiece to reduce thermal cracking, characterized in that it comprises: introducing the alloy workpiece into a metal can, wherein the metal can has a coefficient of thermal expansion smaller than the workpiece. alloy work and includes an inner surface comprising a nickel-boron coating on at least a portion of the inner surface; encapsulate the alloy workpiece in the metal can to provide a canned assembly; remove at least a portion of gas from inside the canned assembly; and heat the canned assembly to the transient liquid phase by joining the alloy workpiece to the metal can.
