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

Abstract

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.
