结合已有的热力学参数和构建的热物理性质数据库,计算预测了合金的摩尔体积和表面能,并同实验数据进行对比,验证了数据库和程序的可靠性.(2)基于纯元素的表面熔化现象,考虑固液界面对熔化过程的影响,结合吉布斯自由能最小化的热力学原理编写了计算程序Cal Na Phad(Calculation of Nano Phase Diagram),耦合输入参数和...
The electrical resistivity of Al-0.10 at% Ag alloy and pure aluminum is measured between room temperature and 500 °C in order to determine the phase diagram at low silver concentrations. The resistivity difference between the alloy and pure aluminum changed corresponding to the phase diagram which...
Based on the Al–Sc phase diagram, when the scandium content reaches the eutectic composition of 0.55 wt% Sc, primary particles of L12 Al3Sc are formed in a eutectic reaction: L + Al3Sc → (Al) at 665 °C, and they in turn act as nucleation sites for α-Al in the molten metal ...
Ternary Phase DiagramExcess PhasisThe effect of the chemical composition, in particular, of alloying with silver (up to 0.6%) and of the Cu-Mg ratio (from 21.2 to 1.6) in alloys of the Al-(2.4–6.3)% Cu-(0.30–2.0)% Mg system on their mechanical properties is studied. Comparative ...
Kondo systems Ce(PdM)Al( M=Cu or Ag ) have been previously shown to display antiferromagnetic (AFM) or ferromagnetic (FM) ordering alternatively then produce a complex phase diagram of AFM-FM-AFM type depending on the substitution amount x . This paper reports the results of specific heat...
