Abstract

In In this study, the microstructure, mechanical and corrosion properties of La and Ca addition to ZM21 Magnesium (Mg) alloy after casting and rolling were investigated. When the microstructure results were examined, it was observed that the secondary phases elongated a little in the rolling direction, while the grains were thinner in the La added alloy after rolling. Differently from this, it was determined that the phases formed in the Ca-added alloy were broken during rolling. According to XRD results, it was observed that MgZn, MgZn2, MgZn3, C5Zn3, Ca2Mg6Zn3, LaZn2, LaMg3 phases were formed in the alloys. Considering the immersion corrosion property, ZM21+0.5(La) Mg alloy experienced less weight loss in both casting and rolling compared to ZM21 Mg alloy. however, ZM21+0.5(Ca) alloy exhibited lower weight loss in cast form and much greater weight loss in rolled form.

Özet

Bu çalışmada ZM21 Magnezyum (Mg) alaşımına La ve Ca ilavesinin döküm ve hadde sonrası mikroyapı, mekanik ve korozyon özellikleri incelenmiştir. Mikroyapı sonuçları incelendiğinde haddeleme sonrasında La ilaveli alaşımda taneler incelirken ikincil fazların bir miktar hadde yönünde uzadığı görülmüştür. Bundan farklı olarak Ca ilaveli alaşımda oluşan fazların haddeleme esnasında kırıldığı tespit edilmiştir. XRD sonuçlarına göre alaşımlarda MgZn, MgZn2, MgZn3, C5Zn3, Ca2Mg6Zn3, LaZn2, LaMg3 fazlarının oluştuğu görüldü. Daldırma korozyon özelliğine bakıldığında ZM21 Mg alaşımına kıyasla ZM21+0,5(La) Mg alaşımının hem döküm hem hadde olarak daha az ağırlık kaybı yaşanmıştır. Fakat döküm halinde ZM21+0,5(Ca) alaşımı daha düşük, haddelenmiş olarakta çok daha fazla ağırlık kaybı sergilemiştir.
