INVESTIGATION OF THE APPLICATION OF VISIOPLASTICITY METHODS OF ANALYSIS TO METAL DEFORMATION PROCESSES. PART I.
Abstract
It was the object of the present investigation to examine the effect that the properties of a material may have on the mechanics of plastic flow in steady-state extrusions. Four materials were chosen for this purpose, which were those affected by strain rates, lead and the eutectic alloy of lead and tin and those affected by work hardening or strain, commercially pure aluminum, and electrolytic copper. The effects of these materials on the configuration of flow will be discussed. The fourth will be discussed in Chapter II, which is the eutectic of lead and tin, which exhibits superplasticity under certain conditions of prestrain and strain rate. In addition to the effects of properties of the material on flow, also extrusion speed and specimen size will be discussed briefly. (Author)
