The Nb-Zn system has been thermodynamically investigated within the CALPHAD approach by combining available experimental data and the data from ab initio calculations of the formation enthalpies for NbZn2, NbZn3 and NbZn15.The isothermal sections at 723 K and 873 K of Zn-Fe-Nb ternary system were thermodynamically optimized where one stoichiometric ternary phase (τ) and the ternary solubility in intermetallic compound (ε) were taken into consideration.The calculated diagrams are in reasonable agreement with the experimental and thermodynamic data.Furthermore, liquidus projection was predicted accordingly.

Cu-Nb基合金的强度和导电性能较好,被广泛应用于电磁脉冲领域.有文献报道,Zr的添加能增强Cu-Nb合金材料的拉伸强度和微观硬度.相图作为材料设计的一种指导工具,对新材料的开发具有重要意义.本实验通过金相显微镜和电子探针分析了Cu-Nb-Zr三元系在900,1000和1100℃温度下的相平衡组织成分(Fig.1),测定了其相平衡关系,确定了900,1000和1100℃三个等温截面图(Fig.2)
随着经济的发展和科技的进步,传统能源正在以惊人的速度消耗,人类正面临着前所未有的能源短缺问题.相变材料可以从环境中吸收能量和向环境中释放能量,能够解决能量供求在时间和空间上不匹配的矛盾,有效提高能源利用率,因此成为当前的研究热点.复合相变材料可以解决单一相变材料的易流动泄漏、导热系数较低等缺陷,在提高能源使用效率和开发利用可再生能源方面具有诱人的应用潜力和广阔的应用前景.本研究以相变储能特性优异的

磁制冷技术是一种极具开发潜力的制冷技术,长期以来具有优异性能的磁制冷材料一直作为人们研究的热点.近年来,Mn基合金及其化合物的磁热效应逐渐受到人们的关注.对Mn2Sb1-xSnx化合物巨磁阻效应的研究也有报道.关于Mn基三元合金相图的研究,迄今为止还没有Mn-Sb-Sn三元系合金的等温截面报道.本实验用高纯度的Mn (99. 5％)、Sn (99. 9%)和Sb (99. 9%)金属作为原材料，在
综合利用X射线粉末衍射(XRD)分析、场发射扫描电子显微镜(FESEM)显微分析和能谱(EDS)分析等方法对Mn-Al-Sb三元系合金相图773 K时的相平衡关系进行了实验测定.结果表明,该截面由11个单相区、20个两相区和9个三相区组成,没有观察到三元金属间化合物存在.
利用扫描电镜和能谱仪,分析研究了熔池中镁对热浸镀45％Al-Zn的镀层组织的影响.实验表明:镁的加入使镀层在生长过程中形成周期性的层状FeAl3,本文对该结构的形成机理作了初步探讨.熔池中镁的加入不能使得基体界面上出现类似于含硅镀层的连续、致密、稳定的二元或三元相。镁不能有效抑制Fe-Al间的剧烈反应，含镁镀层仍出现超厚生长现象。但镀层厚度随镁含量的增加而逐渐减小。在实验研究范围内，在含镁(≥0.
