چکیده انگلیسی
In this study, the room temperature thermal conductivity and microstructure of MgâCe, MgâSm and MgâY binary alloys in as-cast and solution treated conditions were investigated. Quantitative study was conducted on the effect of rare earth elements (in solid solution and intermetallic compounds) on the thermal conductivity of MgâRE alloys. The reduction in thermal conductivity was determined to be about 123.0â¯W/(m·K) and 6.5-16.4â¯W/(m·K), respectively, per 1â¯at.% RE addition in the form of solid solution or intermetallic compounds with Mg. The thermal conductivities of MgâRE alloys were fitted using modified Maxwell and EMT models based on the distribution, volume fractions and shape of intermetallic compounds. The modified structural models provide a good fit to the experimental thermal conductivity data.
