3) The obtained thermodynamic descriptions were implemented into the TCAL database and extensively validated by phase diagram calculations and solidification simulations. The resulting updated database can reliably predict the phase formation in multi-component alloy systems and industrial aluminum alloys. ...

Phase equilibria were investigated in the Al–Pd–Mn phase diagram in the region where quasicrystals and approximant phases form. With respect to previous thermodynamic studies, the extents of the liquidus phase fields of several approximant phases are either established or precisely determined. In part...
CALPHAD (CALculation of PHAse Diagram)技术是一种应用广泛的相图热力学计算方法,可应用于多组元材料的研发与设计,因此很有必要获得多组元铝合金体系的相图与热力学信息,并建立相图热力学数据库。本工作针对A1合金中重要的Al-Cd-Mg三元系及Al-Li-Mg-Mn、Al-Li-Mg-Si四元系富Al角进行了实验测定和相图计算研究...
With the Mn content rising between 8.2 and 12.3 at.%, these deposits have a smooth, nodular surface structure and encompass nanome- ter scale crystals (10–25 nm) of the fcc solid-solution phase coexisting with an amorphous phase. Meanwhile, the hardness of the coatings also increased from ...
