3 Terms and Definitions
For the purposes of this document, the following terms and definitions apply.
3.1
Cold forming
The plastic deformation processing conducted below the recrystallization temperature of workpiece material.
In engineering practice, the plastic deformation processing conducted below the ambient temperature are often referred to as cold forming; and the plastic deformation processing between cold forming and hot forming are referred to as warm forming.
3.2
Hot forming
The plastic deformation processing conducted above the recrystallization temperature of workpiece material.
