Abstract
A system and method of processing an alloy ingot or other alloy workpiece to reduce thermal cracking and reduce friction between the workpiece and the forging die may generally comprise positioning a multi-layer pad between the workpiece and the forging die. An article for processing an alloy ingot or other alloy workpiece to reduce thermal cracking also is disclosed. The present disclosure also is directed to an alloy workpieces processed according to the methods described herein, and to articles of manufacture including or made from alloy workpieces made according to these methods.
Claims23
A multi-layer pad for use during a forging operation, wherein the multi-layer pad comprises:
- a first lubricative layer;
- a second lubricative layer;
- and
- a first insulative layer, wherein the first insulative layer is positioned intermediate the first and second lubricative layers, and wherein at least one of the first and second lubricative layers comprises fiberglass.
A method for processing an alloy workpiece, comprising:
- heating the alloy workpiece to a temperature above an ambient temperature;
- positioning a multi-layer pad between the alloy workpiece and a die, wherein the multi-layer pad comprises a lubrication layer and a thermal resistance layer, wherein the lubrication layer comprises fiberglass;
- and
- hot working the alloy workpiece.
