【摘要】 研究了悬浮浇注对ＺＬ２０１台金组织性能的影响。结果表明：悬浮剂的加入使合金的凝固时间缩短，凝固速度加快，促进了合金结晶组织的细化；当加入３％悬浮剂时合金组织有明显改善，且力学性能σｂ和δ分别提高了８．８％和２３．１％。更多还原

【Abstract】 Abstract The effect of floating casting on the structure and properties of ZL201 alloys is investigated. The resultshows that the adding of floating agent make solidification time shorten and speedfast,refinge structure of alloy. whenthe adding of floating agent is 3%,the alloy structure can be improve obviously and the mechanical properties σb and δmay be increased by 8.8% and 23.I%.[Keywods]AI-Cu alloys floating casting structure properties更多还原
