Abstract: The invention involves a system and method, and multi-layer pad, for processing an alloy ingot or other alloy workpiece to reduce thermal cracking and reduce friction between the workpiece and the forging die. The present invention includes the use of a multi-layer pad when forging a workpiece, which can be positioned between the workpiece and the forging die. The multi-layer pad comprises two layers secured together to form a sleeve, and another layer positioned within the sleeve. The present disclosure is also directed to alloy workpieces processed according to the methods described herein, and to articles of manufacture made from these alloy workpieces.
