Mechanical properties of rapidly solidified Al-Si-Ni-Ce P/M alloys

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