Abstract
Various studies have been conducted on using magnesium alloy instead of conventional iron or aluminum in automobile components, office equipment, home electric appliance, due to the light weight and superior specific strength of magnesium alloy. However, even stronger alloys are needed for structural material. One common way to enhance the strength of magnesium alloy is to increase the Al content. Compacted and solidified billets (preforming) were manufactured using chips (powder) of an AZ91 alloy, and a satisfactory extruding material was obtained by extruding the billets. The report describes the manufacturing of billets from AZ91 chips, extruding of the billets, and studies on the extrusion properties and mechanical characteristics of the extruded material.
