For this purpose, Fe solubility with the change of Mn content and temperature was investigated in the homogenized and re-precipitated liquid AZ91 alloy. The increase of the amount of Mn added to the melt resulted in the decrease of Fe content. The data obtained in this study was adopted to the pilot plant for recycling of the scrap. As a result, Mn and Fe contents measured in the recycled ingot were in good agreement with ASTM B93 standard. 한국재료학회 AZ91 합금 용탕내 Mn과 Fe의 상호용해도 측정 및 AZ91D 재생지금의 성분조정에의 활용 Mutual Solubility of Mn And Fe in AZ91 Alloy Melts and Its Application to Composition Control of AZ91D Recycled Ingots Article 2 한국재료학회지, v.13, no.9, pp.619 - 624 한국재료학회지 13 9 619 624 N kci ART000914195 AZ91D ingot mutual solubility homogenized and re-precipitated liquid AZ91 alloy recycled ingot ASTM B93
