An investigation of the A1-Cu-Cr phase diagram: Phase equilibria at 800 - 1000~C [ J]. Journal of Alloys and Compounds, 2006,417 ( 1 - 2 ) : 121 - 126.B. Grushko, E. Kowalska-Strzeciwilk, B. Przepiorzynski, and M. Surowiec, Journal of Alloys and Compounds 417 , 121 (2006...
The currently accepted Cu-Cr phase diagram was proposed by JACOB et al [15] following a thermodynamic study of the system using the Knudsen cell-mass spectrometry. It falls into the category of simple eutectic, but includes a metastable miscibility gap in the undercooled liquid. Under the ...
基于CALPHAD(CALculation of PHAse Diagram)方法建立多元热力学数据库,结合显微组织表征,性能测定和强化机制的计算,可以进一步研究Ag或Ti的添加对Cu-Cr-Zr合金时效过程中结构演变的热力学和动力学.本工作以Cu-Cr-Zr(-Ag/Ti)体系为研究对象,主要创新研究成果如下:(1)结合文献报道重新评估了Cr-Ag二元系的热力学参数,...

At the aging state, the microstructure, precipitate phase, conductivity and other various properties of these alloys have widely been studied [1-3]. During the aging treatment the supersaturated solid solution decomposes into chromium, CuxZry (Cu3Zr, Cu4Zr Cu5Zr Cu51Zr14)[4-8] particle and...
采用CALPHAD(Calculation of Phase Diagram)技术,对低溶质Cu-Cr-Zr 体系进行了相平衡热力学计算,预测了合金在铸造、热轧和时效温度下可能的析出相和质量分数,以此指导研制合金的化学成分设计。计算结果表明:在低溶质Cu-Cr-Zr 系合金的形变热处理过程中主要存在Cu 相、Cr 相和CusZr 相;当Cr/Zr≥3.5 时,Cr 相为...
Calculation of the nickel-chromium-copper phase diagram from binary data In the solid state the Ni-Cr-Cu system shows a three phase equilibrium between a Cr-rich b.c.c. phase and two f.e.c. phases rich in Ni and in Cu respectively. This rather unexpected feature (Ni and Cu being com...
The phase diagram in the ternary Cu–Cr–Ni system was calculated by a Calphad method. The molar Gibbs energy was expressed by a sub-regular solution model for the face-centered cubic (fcc) phase, the body-centered cubic (bcc) phase and the liquid (L) phase. The ternary interaction ...
