... and microstructure at the surface are far more complex than for a material’s substrate. One of the main challenges of metal forming is understanding the important surface phenomena, such as roughness evolution and friction. 3.1.1 Macroscopic View On the macroscopic scale ( Fig. 3.1a ), it must be recognized...

... extrusion process has a direct influence on the accuracy of the shape and the surface finish of extrusion. The friction between the die/material interface may vary in a complicated manner when metal is flowing through the die opening. The wear process in the die bearing is dependent on the thermodynamics...

Similarly, the temperature rise at the nodal points on the billet container interface and the dead-metal zone conical surface would be calculated by using the frictional heat flux equations and other boundary conditions. Separate boundary conditions are also assumed in the billet...

... ( Fig. 10.1 ), which implies, for a constant reduction, a smaller die angle α . However, this results in a larger surface over which friction is generated. Conversely, a larger die angle reduces the frictional components but leads to increased inhomogeneity; therefore, as in wire drawing, an optimum...
