AZ21 ve AJ21 Magnezyum Alaşımlarının Mekanik Özellikleri ve İşlenebilirliği Üzerine Karşılaştırmalı Bir Çalışma

Bu deneysel çalışmada, Çinko (Zn) ve Stronsiyum'un (Sr) AZ21 ve AJ21 magnezyum alaşımlarının mekanik özellikleri ve işlenebilirliği üzerindeki etkileri araştırılmıştır. Alaşım bileşenlerinin mikroyapıdaki değişime etkisi ve bunların sertlik, mukavemet ile kesme kuvvetlerine (işlenebilirliğe) etkisi incelenmiştir. Deney numunelerinde, alaşım bileşenlerindeki değişimin (%1Zn ve %1Sr), alaşımların mikroyapısını, mekanik özelliklerini ve işlenebilirliğini etkilediği gözlenmiştir. AZ21 alaşımının mekanik özelliklerinin ve işlenebilirliğinin daha yüksek olduğu (kesme kuvvetleri daha düşük) gözlenmiştir. Öte yandan, AJ21 alaşımının ise yüzey kalitesinin daha yüksek olduğu (1.089µm-1.215µm) ve kesme kuvvetlerinin daha yüksek olduğu (55.1N-60.4N) (işlenebilirliğinin daha düşük) görülmüştür.
