Glossary for Binary Phase Diagram Reactions

All the cases of two-phase and three-phase equilibria in isobaric binary phase diagrams are presented. New names are proposed for currently unnamed equilibria.     

Zn-Al系二元相图的研究

利用高温X射线衍射法（XRD）、示差扫描量热分析法（DSC）、热膨胀法（PRD）等方法重新测定Zn-Al二元体系相图。在XRD曲线图中β（ZnAl）相的存在，表明存在β（ZnAl）固溶单相区；DSC曲线图表明在274～279℃范围内存在共析相变反应；PRD曲线图表明在340℃不存在相变反应。综合XRD、DSC和PRD结果，绘制了部分Zn-Al二元体系相图，为高铝锌基合金的实际相变应用提供参考。     

Low Temperature Thermodynamic Study of the Stable and Metastable Phases of Silver

The low temperature thermodynamics of the stable phase of silver was assessed by the polynomial model and Debye model from the experimental data available in the literature. By means of the constrained non-linear least squares curve fitting arithmetic, two sets of parameter values were determined. The expression of the thermodynamic functions cp(T) and G(T)-H (298.15K) at 0-298.15K were presented. Only the low temperature thermodynamics of the metastable phase of silver can be extrapolated by the Debye model. The expression of the thermodynamic functions cp(T) at 0-298.15K was presented.     

Gasar工艺中金属-氢二元相图的研究

Gasar工艺中常用非气体化合物形成元素的金属与气体组成的二元系统在定向凝固时发生共生生长来制备规则多孔金属材料．本文分析了此类金属一气体二元系统的相图特点，对此类二元系统的相图计算的原理进行了探讨，并实际计算了Cu-H相图．     

纳米金属微粒二元相图的尺寸效应和形状效应

通过考虑相图计算公式中基本参数——熔化温度和熔化焓的尺寸效应与形状效应,研究了完全互溶的二元纳米金属微粒系统理想溶液的相图．研究结果表明,纳米微粒的相图也依赖于微粒的尺寸和形状因子．对Cr-Mo纳米微粒系统相图的计算结果表明,纳米微粒相图的固相线和液相线要比相应块体材料的固相线和液相线低,但与已报道的结果不同的是,固、液相线变化的幅度基本相同．这与本文目前不仅考虑了纳米微粒熔化温度的影响,还考虑了纳米微粒熔化焓的影响有关．     

The Hafnium-Platinum Phase Diagram

Phase relationships were determined in the Hf-Pt system at temperatures up to 1690 °C using both metallographic and neutron Rietveld refinement techniques. An unusual displacive transformation is observed below 200 °C in the rhombohedral compound Hf₃Pt₄, similar to that recently discovered in the compound Zr₃Pt₄. Crystallographic data are presented for the compounds HfPt₄, HfPt₃, Hf₂Pt₃, Hf₃Pt₄, HfPt, and Hf₂Pt. A complete phase diagram is presented for the Hf-Pt binary system.
