Abstract
In conjunction with the previous analysis on core fracture [1, 2], a criterion for prevention of sleeve fracture in extrusion of bimetal rods is developed. The sleeve fracture is likewise affected by a set of independent process parameters, namely the reduction in area, die angle, friction, interfacial bonding, relative size, and relative strength of the sleeve. It is shown that the usage of the present criterion for sleeve fracture and the criterion previously described for core fracture can provide an effective path to a successful extrusion operation for bimetal rods and wires.
