Phase Diagrams and Physical Properties of Nonequilibrium AlloysNonequilibrium Phase Diagrams of Ternary Amorphous AlloysSummary This document is part of Subvolume A 'Nonequilibrium Phase Diagrams of Ternary Amorphous Alloys' of Volume 37 'Phase Diagrams and Physical Properties of Nonequilib...
Phase diagrams of quasicrystal-forming alloy systems, such as Al-Cu-Fe, are essential to the continued development and fundamental understanding of quasicrystalline alloys, especially for the synthesis of single quasicrystals. Isothermal sections of the Al-Cu-Fe system at 700, 800, and 1000 °C...

图1 Al-Cu二元相图[6-7] Fig.1 The Al-Cu phase diagram[6-7] 1 材料与方法 实验中选用Al柱(99.99 wt%)和Cu块(99.99 wt%)作为原始材料。将金属切成5 mm×5 mm×5 mm的立方体。将这些立方体镶嵌后,在酒精中用240～3 000目的砂纸从粗至细依次进行打磨,最后用钻石膏抛光,以此来获得高质量的表面。将...
Cast Al-alloys mainly contain Si, with Cu and Mg as minor alloying elements. The addition of Si forms a classical eutectic system, improving castability and fluidity [31,33]. The phase diagram (Fig. 2(a)) shows a eutectic point at ca. 12.7 wt% Si and 579 °C and the ...

Analysis of these alloys, however, still requires the knowledge of the six-component Al–Cu–Fe–Mg–Ni–Si phase diagram. Assessment of such a complex system is a very challenging task, as all constituent elements can form different phases whose selection depends on the ratio between these ...
其最重要的成果之一是首次发现了Al-Zn–Cu 系中存在的新三元化合物T´相，并且有一定的成分范围。同时明确了低Cu 侧的化合物与三个固溶体相的相平衡关系。低Cu 侧的fcc 固溶体溶解度间隙形状在350℃时仅在40at%Zn 含量左右存在极小的成分范围，而且不存在T´+α1+α2三相区，他们的结果又表明Cu 的添加...
