Abstract: The effect of extrusion on grain refinement has been studied in the AZ91 cast ingots. It is found that grain size smaller than 10μm can be obtained by the extrusion processing. Vickers hardness measurements were also carried out to evaluate the effect of these processes on the room temperature mechanical properties. ...
