. It was suggested that the microstructure evolution of the alloy during the solid solution treatment was concluded as follows: Mg5(GdEr) eutectic phase→Gd/Er atom diffusing into matrix→spheroidic Mg5(GdEr) phase→cuboid-shaped RE-rich phase→grain boundary immigration. Key words: Mg-Gd-Er-Zr alloy; microstructure evolution; solution solid treatment; eutectic phase 1 Introduction As a result......

sensitivity of solid fraction decreases with increasing solid fraction or with decreasing temperature above eutectic reaction temperature of AM60 alloy. When the solid fraction φs is 0.4, corresponding... temperature range (ΔT). It is usually defined as the temperature range between the solidus and the liquidus of an alloy. The solidification temperature range of pure metal and eutectic alloys is zero......
that the terna-ry Al-Si-Mg2Si eutectic reaction is depressed when Fig.2 DTA curves of Al-7%Si-0.55%Mg alloy at various cooling rates Table 4 DSC cooling characteristics of as-cast Al-7%Si-0.55%Mg... a two-dimensional visualization of a section of the complex Al-Si-Mg ternary system[15]. The eutectic temperature of an Al-Si alloy for a given Mg content can roughly be estimated by following......
