ARTICLES, SYSTEMS, AND METHODS FOR FORGING ALLOYS

摘要

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.

1. A system for forging a workpiece, the system comprising:
a die; an alloy workpiece; and a pad positioned intermediate at least a portion of the die and at least a portion of the alloy workpiece, wherein the pad comprises a plurality of layers including:
a first layer comprising a first thermal resistance and a first coefficient of friction; anda second layer comprising a second thermal resistance and a second coefficient of friction, wherein the first thermal resistance is greater than the second thermal resistance, and wherein the first coefficient of friction is greater than the second coefficient of friction.
