Abstract The phase diagram of Zn2Al binary system was inves2 tigated by means of differential scanning calorimeter (DSC) , X2ray diffraction (XRD) and pushrod dilatometer (PRD). Ad2 vents ofβ(ZnAl) phase on XRD curves indicates that there ex2 ...
The room temperature phase diagram of Al-Zn-Cu system is the important basis for judging the phase constituents of the materials at the usage condition. New results about the room temperature phase diagram of the low copper side in the Al-Zn-Cu systems have been shown in this study. Miscibi...
The covalent bond of Al 37 Zn 1 Mg 2 was stronger than that of Al 49 Zn 2 Mg 1 and Al 34 -Zn 1 Mg 1 , and the structure of Al 37 Zn 1 Mg 2 was the most stable.Key words phase diagram, second phases, solid solutions, formation enthalpy, cohesive energy, intrinsic properties0...
Based on the criteria of thermodynamics (phase diagram extrapolations) and mechanical behavior (flow curves), it was possible to select the Zn-Al-Ga alloy as best meeting the requirements concerning melting range necessary for die attach and mechanical properties. A wire with 0.76-mm thickness ...

The Al-Zn phase diagram which shows the dependence of the free energy and the lattice parameters on the composition and the temperature is presented. The X-ray experiments carried out with mono and polycrystals confirmed the discontinuous mode of the η-phase formation as well as the proposed ...
Mg32(Al,Zn)49相3) Ti-Al phase diagram Ti-Al相图 1. Introduces valence electron structures of solid phase in Ti-Al phase diagram,calculates solubility of interstitial elements. 阐述Ti-Al相图固相的价电子结构,计算了间隙元素的溶解度。4) Gd-Co-Al phase diagram Gd-Co-Al相图5...
According to the Zn-Al binary phase diagram, zinc atoms do not form intermetallic compounds with aluminum, and their solid solubility does not exceed 5% [28]. The decrease in copper content is attributed to the formation of the intermetallic compound AlCu3 between the excess aluminum and copper...
在凝固模拟研究中,相图计算法CALPHAD(Calculation of phase diagram)得到了广泛 的应用。目前,国际上应用相对成熟的相图计算软件 有 Thermo-Calc、Thermosuite、Jmat- 9、Pro、MTDATA、 FACT 和 PANDAT 等,相应的相图热力学数据库有 SGTE(纯物质、溶液和化合物)数据库、金属基(Fe 基、 Ni 基、Ti 基、Al 基和 ...
