Moreover, the predicted values of the reduced heat of transport (the quantity which explicitly characterizes both the magnitude and direction of thermotransport) in Ni-Al melts, reveal fairly weak composition dependence while being practically independent of temperature at all. Accordingly, in the presence of a temperature gradient, our simulation results for the models of liquid Ni25Al75, Ni50Al50 and Ni75Al25 alloys predict consistently Ni and Al to migrate to the cold and hot ends, respectively. Meanwhile, the highest value, about 1.1 ± 0.1 eV, of the reduced heat of transport is observed for Ni50Al50 alloy model and it slightly decreases towards Al-rich and Ni-rich compositions.]]> Wed 11 Apr 2018 18:28:27 AEST ]]> Computer simulation of thermodynamic factors in Ni-Al and Cu-Ag liquid alloys https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:48571 0. On the other hand, for the total and Faber-Ziman partial structure factors, good agreement is observed only for q values outside the limit q->0. In addition, a similarity between the shapes of the thermodynamic factor composition dependence and the shape of the liquidus lines in both Ni-Al and Cu-Ag liquid alloys is noted. We highlight the significance of the presented computational and experimental study for developing and testing various models and frameworks.]]> Tue 21 Mar 2023 16:12:47 AEDT ]]> Molecular dynamics simulation of surface segregation in a (110) B2-NiAl thin film https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:18160 Sat 24 Mar 2018 08:04:38 AEDT ]]> Theoretical study of the heat of transport in a liquid Ni50Al50 alloy: Green-Kubo approach https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:17348 Sat 24 Mar 2018 08:01:40 AEDT ]]> Thermotransport in binary system: case study on Ni50Al50 melt https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:18823 Sat 24 Mar 2018 07:51:08 AEDT ]]> Influence of the interatomic potential on thermotransport in binary liquid alloys: case study on NiAl https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:30178 50Al50 melt with the embedded-atom method potential developed in [G.P. Purja Pun, Y. Mishin, Phil. Mag., 2009, 89, 3245]. The principal objective of the work is to quantitatively characterise and analyse thermotransport in the system, i.e. diffusion driven by a temperature gradient. In addition, direct phenomenological coefficients for mass and thermal transport are also evaluated and analysed in the process. Furthermore, the results obtained are compared with previously published data for a different model of Ni50Al50 melt with an alternative embedded-atom method potential for the alloy as well as with experiment where possible. It is found that both potentials are able to consistently predict both direct transport coefficients over a wide temperature range. However, these two potentials are found to be inconsistent in characterising the cross-coupled heat and mass transport, predicting even different directions (sign) of the heat of thermotransport. The origin of this difference is discussed in the paper in detail.]]> Sat 24 Mar 2018 07:26:15 AEDT ]]> Interdiffusion and thermotransport in Ni-Al liquid alloys https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:45841 21.5Al78.5 melt (only qualitative result is available so far).]]> Mon 07 Nov 2022 14:03:09 AEDT ]]> Mass and thermal transport in liquid Cu-Ag alloys https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:47755 Fri 27 Jan 2023 10:17:51 AEDT ]]>
