Interdiffusion in the Ni-Re System: Evaluation of Uncertainties
(2017-06-22)
Diffusion couple experiments between Ni and Re at 1200 and 1350 °C were performed. These experiments established the limits of the two-phase FCC + HCP region. No intermediate phase was observed at these temperatures. ...
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 ...
