Internal stress in the Al extrusion

  1. Jun 19, 2013 #1
    Can anybody tell the stress developed during extrusion of Al Alloy. More importantly, is there a type of Al alloy that prefer least amount of stress.

    work hardening I would think. Prefer the least amount of stress...I think it would be an aluminium that has undergone significant Ostwald ripening.

    It will also depend on the temperature of extrusion. Higher temperature - less stress.
