The effect of pressure and temperature variations on the FEM prediction of deformation during extrusion [PDF]

open access: yes, 2005
The extrusion process is complex, involving interaction between the process variables and the material’s high temperature properties and is typically conducted at relatively high temperatures because the lower flow stress of the material permits larger ...

Influence of plastic formation parameters on structural characteristics of thermoelectric material during hot extrusion

open access: yesModern Electronic Materials, 2017
We used mathematical modeling to compare the stress and deformation in a Bi0.4Sb1.6Te3 solid solution base thermoelectric material for extrusion through different diameter dies. The results show that extrusion through a 20 mm diameter die produces a more
