Appl. No.:

15/344637

Inventors:

- Albany OR, US
Ramesh S. Minisandram - Charlotte NC, US
Christopher M. O'Brien - Monroe NC, US

International Classification:

B21J 13/02
B21J 3/00
B21J 1/06

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.

Abstract:

Processes and methods related to processing and hot working alloy ingots are disclosed. A metallic material layer is deposited onto at least a region of a surface of an alloy ingot before hot working the alloy ingot. The processes and methods are characterized by a reduction in the incidence of surface cracking of the alloy ingot during hot working.
