Dies usually fail by spalling and crumbling of the thread crests, which roughen the minor diameter of the product thread...

...: brittle fracture and tribo-oxidative wear. High friction coefficients during sliding generate high tensile stresses in the wake of the contact area ( Ref 134 ). If sufficiently large flaws exist, cracks form, grow, and ultimately lead to faceted wear debris formation. Figure 20 shows such features...

...; hence the volume fraction of core in the product is the same as that in the billet. If this is not the case, sliding must occur at the core/clad interface in the deforming region. This can happen when the flow characteristics of the core and clad are sufficiently different that a hard clad acts as a die...
