... at the periphery. In the corner of the leading end of the billet, a separate metal zone is formed between the die face and the container wall, known as a dead-metal zone. The material near the surface undergoes shear deformation compared with the pure deformation at the center, and it flows diagonally into the die...

Full-Film Lubrication Full-film lubrication exists when a thick layer of solid lubricant/dry coating is present between the dies and the workpiece. In this case, the friction conditions are governed by the shear strength of the lubricant film...
