Thesis title: Experimental Investigation of the Phase Equilibria in the Mg-Mn-{Ce, Nd} and Ce-Mg-Zn Ternary Systems and Diffusivity Measurements of the Mg-{Ce, Nd, Zn} and Zn-{Ce, Nd} Binary Systems
Summary: In this work, the 450°C Mg-Mn-{Ce, Nd} and 300°C Ce-Mg-Zn isothermal sections were established using diffusion couples and key alloys. The phase relationships were determined using XDR, EDS/WDS and metallography. Diffusion couples were also used to measure the interdiffusion coefficients of the Mg-{Ce, Nd, Zn} and Zn-{Ce, Nd} binary systems based on the experimental composition profiles and Boltzmann-Matano method.
- MSc Thesis, September 2006 - September 2009
Institute: Industrial Engineering/Design and Manufacturing Department at Jordan University.
Thesis title: Effect of addition of Hf on the Mechanical Behavior and Wear Resistance of ZA5 Alloy
Summary: The ZA5 alloy melt solidifies with dendritic structure of large grain size, which affects its mechanical behavior and surface quality. This alloy is normally grain refined by some refiners like Titanium or Titanium+Boron additives. In this work, the effect of addition of hafnium (Hf) at different weight percentages, ranging from 0.02% to 0.12%, to ZA5 as a grain refiner on its micro structure, hardness, mechanical behavior and wear resistant, was investigated.
