Tensile Properties of Large Extrusion and Forgings of RS P/M Al-9Fe-1.9Mo-1.7Si Aluminum Alloy

Large extrusion and forgings of Al-9Fe-1.9Mo-1.7Si (wt.%, FMS0918) aluminum alloy for elevated temperature applications were produced by rapidly solidified powder metallurgy process. Powders of FMS0918 alloy were produced by inert gas atomization, and then screened, canned, degassed, extruded and forged. The extrusion exhibited good strengths and elongation in longitudinal orientation, but low elongation in long- and short-transverse orientations. After forged, the tensile strengths of the forgings showed little change, but the long- and short-transverse elongation was improved.
