    摘要:
    摘要:通过在高频和隔热炉中使用铌安瓶作为坩埚,通过不同的退火序列从元素合成了金属间化合物CeCuMg和GdCuMg以及三元Laves相 RECu4Mg (RE=Sm, Gd–Tm)。通过X射线粉末衍射(Guinier技术)对所有样品进行晶格参数表征。从单晶X射线衍射仪数据中精制了两种结构:a=764.75(6) pm, c=414.25(4) pm, 空间群P62m, wR2=0.0389, 338F2值,CeCuMg的15个参数(ZrNiAl型)和a=723.18(2) pm, 空间群F43m, wR2=0.0818, 91F2值,Gd1.06(3)Cu4Mg0.94(3)(MgCu4Sn型)的八个参数。Laves相显示出小的均质范围(Gd/Mg混合)。对铁磁性GdCuMg(ZrNiAl型;TC=82 K)的磁熵变化(ΔSM=6.5 J kg−1K−1)和相对冷却功率(RCP=260 J kg−1)进行了磁热效应(MCE)研究,对于从0到70 kOe的磁场变化,将GdCuMg分类为80 K区域的中等磁热材料。在Laves相RECu4Mg中,SmCu4Mg在Néel温度10.8(5) K以上表现为范-弗莱克顺磁性,而GdCu4Mg和TbCu4Mg在约48 K和30 K处经历反铁磁相变。TmCu4Mg在整个温度范围内显示居里-魏斯行为。对SmCu4Mg的电阻率和GdCu4Mg的比热容进行了进一步表征。

  • On the Origin of the Negative Thermal Expansion Behavior of YCu

    which is stabilized by internal energy. At higher temperatures, Cu ions are bound loosely with Y ions due to the large Y–Cu distance (3.01 Å), which results in large vibration entropy and stabilizes a CsCl-type crystal structure. In addition, the CsCl-type structure is reinforced by the Y–Y interaction between next-nearest neighbors, resulting in a smaller unit cell volume. The crystal structure has
    属间化合物和合中,YCu是一种不寻常的材料,因为它显示出负热膨胀而没有旋转序。由YCu的结构相变引起的此行为背后的机理尚未完全了解。为了深入了解这种机理,我们通过实验检查了YCu低温相的晶体结构,并借助热力学计算讨论了相变的起源。结果表明,高温(立方CsCl型)到低温(正交FeB型)结构相变是由三个共价键Y-Cu,Y-Y和Cu-的重排驱动的,它们竞争结合能和声子熵。在低温下 Y和Cu的混合不容易发生,因为从较小的负混合焓预期这些原子之间的吸引力很弱。这导致所有三种相互作用都参与键合,并且Y和Cu分离形成FeB型结构,并通过内部能量使其稳定。在较高的温度下,由于较大的Y-Cu距离(3.01Å),Cu离子与Y离子松散结合,这导致较大的振动熵并稳定了CsCl型晶体结构。另外,CsCl型结构通过最近邻之间的Y-Y相互作用得到增强,从而导致较小的晶胞体积。晶体结构具有简单的Y立方结构,其中含Y的Cu离子在空穴位置松散地结合。

    The binary Ce-Cu system has been re-investigated via the selected eighteen key alloys by means of the differential scanning calorimetry (DSC), X-ray diffraction (XRD), and scanning electron microscopy (SEM) with energy dispersive X-ray analysis techniques. Five intermetallic compounds, Cu6Ce, Cu5Ce, Cu4Ce, Cu2Ce, and CuCe, have been confirmed. Cu6Ce and Cu2Ce melt congruently at 947 degrees C and 810 degrees C, respectively. Cu5Ce, Cu4Ce, and CuCe are formed through peritectic reactions, L + Cu6Ce <-> Cu5Ce at 799 degrees C, L + Cu5Ce <-> Cu4Ce at 792 degrees C, and L + Cu2Ce <-> CuCe at 492 degrees C, respectively. Three eutectic reactions, L <-> (Cu) + Cu6Ce at 879 degrees C, L <-> Cu4Ce + Cu2Ce at 753 degrees C, and L <-> CuCe + (gamma Ce) at 407 degrees C, have been observed. One catatectic reaction, (delta Ce) <-> L + (gamma Ce) at 702 degrees C, was determined. According to the present experimental results, the Ce-Cu phase diagram is revised. (C) 2011 Elsevier B.V.

    The phase relations of the ternary system Ce-Al-Cu in the Cu-poor part at 503 K were investigated by X-ray powder diffraction (XRD). The investigated composition region consists of 16 single-phase, 32 two-phase and 17 three-phase regions. At 503 K, the maximum solid solubilities of Cu in Al, alpha-Ce3Al11, CeAl3 and CeAl2 are about 2.5 at.%, 1.6, 3.6 and 5.3, respectively, and Al in CeCu5 is about 39.2 at.% The homogeneity ranges of Al2Cu and AlCu phases extend from about 32.1 to 32.6 at.% Cu and 49.7 to 52.4 at.% Cu, respectively. Five ternary compounds and their solid solutions have been observed in this work: CeAl12-xCux (4.0 <= x <= 4.52), Ce2Al17-xCux (6.50 <= x <= 7.55), CeAl13-xCux (6.62 <= x <= 6.92), CeAl4-xCux (0.74 <= x <= 1.10) and CeAlCu.
