摘 要：<正> The metastable extension of solid solubility and age hardening of rapidly solidified Al-Er alloy were inves-tigated.The splat foils（0.04～0.06 mm in thickness）and spun ribbons（0.02～0.04 mm in thickness）of Al-Eralloys were prepared by melt hammer-anvil and melt spinning techniques,respectively.The cooling rate wasabout 106～107 K/s.The metastable extended solid solubility of Er in Al evaluated by measurements of lat-tice parameters of rapidly solidified alloys was 0.75 at%.An age hardening response was observed in thequenched and aged specimen.The precipitate responsible for age hardening was identified to be Cu3Au typecubic Al3Er.
