Bazı Magnezyum Alaşımlarında Sürünme Hızı, Termal İletkenlik ve Karışım Entalpisi Arasındaki İlişkinin İncelenmesi

Abstract

Magnesium (Mg) and its alloys are known for their high specific strength, but they have limitations that need to be addressed to expand their range of industrial use. One major limitation is their high temperature performance, which requires improvement for them to be used in industries such as aviation where creep resistance is important. In this study, we investigated the creep behavior of several Mg alloys, including the commercially used AZ series (AZ31, AZ61, and AZ91), as well as the AM50, AX52, and AE42 alloys. We studied the relationship between the creep rate of these alloys and two material properties: thermal conductivity and enthalpy of mixing. By analyzing these properties, we can compare and evaluate newly developed or existing alloys in terms of their creep behavior. When the obtained results are interpreted in general, a linear relationship is found between the creep rate, thermal conductivity and enthalpy of mixing as a general trend.
