Methods of thermo-mechanically processing tool steel and tools made from thermo-mechanically processed tool steels

A method of thermo-mechanically processing a preform (64) composed of tool steel and a tool (18) to modify a workpiece (28). The preform (64) has a region containing austenite. The method comprises establishing the region at a process temperature between a martensitic start temperature and a stable...
