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,...
We find, contrary to the assumption based on equilibrium phase diagram, that in this non-equilibrium case most of the grain refinement and most of the hardness enhancement (from 2.5-3 to 4-5 GPa) takes place in the compositional range (up to 3 at.% Zr) where many or even most Zr...
According to the Al-Zr phase diagram, the maximum equilibrium solubility of Zr in Al is ~0.25 wt% [21]. The absence of Zr-rich precipitates in the gas atomized powders of the alloy with 0.5 wt% Zr reflects the increase in the solubility originated by the high cooling rate involved ...
Phase diagram and phase equilibrium simulations were performed with the composition of 7xxx alloy, as outlined in Section 2.2. 2.2. Alloy Processing The materials used in this investigation are Al-Zn-Mg-Cu-Zr aluminum alloys within the composition range of 7449 aluminum alloy. To investigate the...
