Development of high-strength aluminum-based alloys by synthesis of new multicomponent quasicrystals

摘要

By the ocntrol of composition,Clustered atomic configuraiton and stability of the supercooled liquid in the rapid solidification and posder metallurgy processes,high-strength Al-based bulk alloys containing nanoscale nonperidoic phases were produced in Al-Ln-LTM.Al-ETM-LTM and Al-(V,Cr,Mn)-LTM (Ln=lanthanide metal LTM=VII and VIII group metals,ETM-IV to VI group metals) alloys containing high Al contents of 92 to 95 at
