A method of processing an alloy workpiece to reduce thermal cracking comprises inserting the alloy workpiece into a metallic canister, wherein the metallic canister has a lower coefficient of thermal expansion than the alloy workpiece and includes an inner surface comprising a nickel-boron coating on at least a portion of the inner surface, encapsulating the alloy workpiece in the metallic canister to provide a canned assembly, removing at least a portion of gas from the interior of the canned assembly, and heating the canned assembly to transient liquid phase bond the alloy workpiece to the metallic canister.
