Review of Some Recent Research on Cold Extrusion 640122

The stresses developed during cold extrusion are so high that more accurate stress estimates are necessary for judging the limitations in applying the process to a particular application. This paper reviews a few research investigations dealing with the effects of variables in cold extrusion processes on punch pressures and limiting reductions without cracking. Some information is also presented about the effects of processing and elevated temperature working on strength of parts.
