Experimental Investigation and Thermodynamic Modeling of the Co-Rich Region in the Co-Al-Ni-W Quaternary System
(2017-03-20)
The stabilities of the γ-(Co), γ′-Co3(Al,W), μ-Co7W6, β-CoAl and α-(W) phases in the Co-Al-W and Ni-Al-W ternary systems were investigated at 900, 1000, 1100 and 1300 °C. Electron probe microanalysis was used to determine ...
Thermodynamic Description of the Ti-Al-O System Based on Experimental Data
(2017-06-08)
Phase equilibria of the TiO2-Al2O3 system were investigated experimentally using XRD, SEM/EDX and DTA methods. Temperature stability limits of the aluminum titanate (Al2TiO5) were detected. The thermodynamic parameters of ...
Thermodynamic analysis of the topologically close packed σ phase in the Co-Cr system
(2019-11)
Density functional theory (DFT) calculations show that it is essential to consider the magnetic contribution to the
total energy for the end-members of the σ phase. A more straightforward method to use the DFT results in ...
Thermodynamic assessment of the Co-Ta system
(2018-12)
The Co-Ta system has been reviewed and the thermodynamic description was re-assessed in the present work.
DFT (density functional theory) calculations considering spin polarization were performed to obtain the energies
for ...
