FORMATION OF BALL RARE-EARTH PHASE IN PURE Al AND Al-Mn ALLOY
纯Al及Al-Mn合金中球状稀土相的形成

The effective determination to the morphology,composition and distribu-tion of ball rare-earth phase in pure Al and Al-Mn alloy was studied in this paper.The re-sults show that proper content of rare-earth can globe the polygonal block compound inaluminiu
