TOOLS WITH A THERMO-MECHANICALLY MODIFIED WORKING REGION AND METHODS OF FORMING SUCH TOOLS.

摘要

Tools with a thermo-mechanically modified working region and methods of forming such tools. The tool includes a working region containing steel altered by a thermo-mechanical process to contain modified carbide and/or alloy bands. In use, a surface of the working region contacts a workpiece when the tool is used to perform a metal-forming operation.
