Extrusion of Clad Metals.

摘要

Criteria for the prevention of fracture of the hard core during extrusion of a hard core in a soft container are presented. The extrusion ram force is also calculated. The criteria and the ram force are functions of: The ratio of the core strength to the strength of the capsule in which the core is contained;The reduction in area;The relative radius of the core;the core radius over the container radius;The semicone angle of the extrusion die;The friction factor;The relative mean pressure. The results are presented in mathematical form,and in graphical form for a limited range of variables. (Author)
