To meet current and future materials needs for structural members or engine parts in aircraft, motorcycle and automobile, it is needed to develop high-performance light weight alloys with higher room-temperature strength, higher elevated temperature strength, higher wear resistance and lower thermal expansion. Powder metallurgy (P/M) alloys with novel mechanical properties have been developed by a rapid solidification technique. The improved properties result from structural modifications such as reduction of segregation, refinement of grain size and increase in solid solubility limit. The aim of this paper is to examine the effect of adding of glass-forming elements, Ni and Ce, to a RS P/M Al-19at.%Si alloy for the development of high strength and good wear resistance aluminum alloys.
