拉强度达到了 49708MPa,并没有发现 Mn含量增 加会降低合金塑性的证据。 Mn、Cr、Zr和Er共同作用形成 Al12(Mn、Cr)和Al3(Er、Zr)第二相,极大地提高了合金硬度。 图6 AlMn二元合金相图 Fig.6ThephasediagramofAlMnbinaryalloy 图7(a)～图7(b)为AlMgMn合金中 Al6Mn 相的透射图像,可知其形貌为短棒状,当...
Mn相属于高温稳定相,用于实验的A1Mn djffractiondiagram 0fAI,Mnphase 相样品中有可能与成份接近的其它A1一Mn相共存.用于 部分衍射斑点给出了标定指数 x射线衍射实验的AI;Mn样品中如果同时存在步量的其 强衍射点里伪十次对称分布. 它AI～Mn相,则无疑会造成实验结果的偏差. 我们在实验 中使用 已确定的Al。Mn...
(see experimental points in the Al–Mg phase diagram, Fig.1) during long time (between 4000 h at 210 °C and 600 h at 440 °C), and then quenched in water. The accuracy of the annealing temperature was ±2 °C. After quenching, samples were embedded in resin and then mechanically ...
To date, QCs have been reported and confirmed in over one hundred different alloy systems based on Al, Cr, Cu, Fe, Ga, Mg, Mn, Ni, Ta, Ti, V, Zn, Zr, and other metals [[5], [6], [7], [8], [9], [10]]. Among them, the Al-Cu-Fe ternary alloys have attracted ...

基于Ginzburg-Landau理论采用连续相场法模拟了Fe-15%Cu-3%Mn-x Al(质量分数x = 1%, 3%, 5%)合金在873 K等温时效时纳米富Cu析出相沉淀机制及Al含量对富Cu相析出的阻碍效应. 通过计算成分场变量和结构序参数, 研究了富Cu析出相的形貌、颗粒密度、平均颗粒半径、生长和粗化动力学. 研究结果表明:在时效早期阶段,...
To the present authors’ view, the limitations of the proposed criterion/rule are from their starting bases, e.g., the deep eutectic rule was based on the equilibrium phase diagram and the size difference rule was based on the atomic sizes of the constituent elements and these starting bases...
The phase diagram of the Al-Er-Zr ternary system at 773K has been experimentally investigated by means of x-ray powder diffraction (XRD), differential thermal analysis (DTA) and scanning electron microscopy (SEM) with energy dispersive analysis (EDX). The existence of 13 binary compounds, i....
