“…Cold drawing, in its historical context in metal forming, has also been reported [6]. Increases in tensile strength of cold rolled polymers have been reported [7] and biaxial cold rolling improved the deep drawability of polymers [8]. Perhaps because of its attractive combination of properties (strength and ductility), polycarbonate (PC) has been used in many of these studies.…”

Polycarbonate was subjected to various combinations of mechanical-thermal histories to investigate such effects on subsequent tensile mechanical properties. This was accomplished by "cold extruding" the material initially; nominal "reductions in area" of 18, 40 and 64% were used. Cold extruded bars were then heat treated at three temperature levels, all being less than T z (150°C) of polycarbonate. As compared with the material that was only cold extruded, it was found that in general, heat treating tends to raise the yield stress while lowering the tensile strength, elastic modulus and stress at fracture. The results suggest that a desired combination of properties may be obtainable by the use of a cold work-heat treating sequence.
