The temperature distribution during a steady axisymmetric extrusion process is calculated for a material with temperature-sensitive properties. Numerical results are obtained for Ti-6Al-4V. The extrusion process involves large deformations at high rates, and therefore large temperature changes are produced by the conversion of plastic work to heat. It is found that one must consider this adiabatic heating since temperature changes can easily be as large as 400°F. One cannot replace the temperature change with a uniform increase if one desires to calculate stresses.
