摘要：
The microstructure and properties of the Al-5Si-1.3Cu-0.4 Mg-0.15Zr alloys with Yb or Gd additives were investigated. Al4Si4Yb/Al10Si4Yb and Al15Cu2Si2Gd eutectic phases were identified in the investigated alloys. The compression YS at room temperature and 200 degrees C significantly increased in the rare earth metals doped alloys in the quenched and aged state.
