Research work

Ph.D thesis work:

'Experimental Investigation and Thermodynamic Modeling of the Mg-Cu-Ni-Y Quaternary System'

Summary of the project:

In this work, a self-consistent thermodynamic database for the Mg-Cu-Ni-Y system has been constructed by combining the thermodynamic descriptions of the constituent binary and ternary sub-systems. The modified quasichemical model has been used to describe the liquid phase in this system, for the first time, which accounts for the short range ordering. Isothermal sections of the Mg-Cu-Y and Mg-Ni-Y systems at 673 K and Cu-Ni-Y system at 973 K have been constructed experimentally. Diffusion couples and key samples have been employed for establishing the phase equilibria. Microstructure characterizations using scanning electron microscopy (SEM), and phase identification using x-ray diffraction (XRD) and wave dispersive x-ray spectrometer (WDS) have been carried out. Several ternary intermetallic compounds have been identified in the Mg-Ni-Y system. Crystallographic prototypes of two of these compounds; MgNiY4 and MgNi2Y2 have been found and their lattice parameters have been determined using Rietveld analysis of the XRD patterns. Also, ternary solubility of MgNi4Y has been found. Ternary solubility of the binary compounds in the Mg-Cu-Y, Mg-Ni-Y and Cu-Ni-Y systems has been determined. A complete mutual solubility between CuY-NiY and Cu4Y-Ni4Y in the Cu-Ni-Y system has been identified. Differential scanning calorimetry (DSC) experiments have been conducted for selected key samples of the Mg-Cu-Y, Mg-Ni-Y and Cu-Ni-Y systems to determine the liquidus and other phase transformation temperatures. These results have been compared with the thermodynamic modeling which showed good agreement. Thermodynamic calculations of the Mg-Cu-Ni system also show consistency with the literature data.

Liquidus projections of the four ternary systems have been calculated based on the present thermodynamic modeling considering the current experimental results and data from the literature. All four ternary systems have been combined in one database for the Mg-Cu-Ni-Y quaternary. .

M.A.Sc thesis work:

Thermodynamic Modeling of the Mg-Cu-Y System Mezbah M.A.Sc thesis

Summary of the project:

Thermodynamic modeling of the Mg-Cu-Y system is carried out as a part of thermodynamic database construction for Mg alloys. This system is being modeled for the first time using the Modified Quasichemical model which considers the presence of short range ordering in the liquid.
A self-consistent thermodynamic data base for the Mg-Cu-Y system is constructed by combining the thermodynamic descriptions of the constituent binaries, Mg-Cu, Cu-Y, and Mg-Y using a suitable ternary extrapolation technique. All the three binaries have been re-optimized based on the experimental phase equilibrium and thermodynamic data available in the literature.
The constructed database is used to calculate and predict the thermodynamic properties, binary phase diagrams and liquidus projections of the ternary Mg-Cu-Y system. Calculated phase diagrams and the thermodynamic properties such as activity, enthalpy of mixing and partial Gibbs energy of the binary liquid alloys are found to be in good agreement with the experimental data reported in the literature. Moreover, for the Mg-Cu-Y ternary system, isothermal sections, vertical sections and polythermal sections are calculated, and the invariant reaction points are predicted for the first time.
