ACADEMIC BACKGROUND

2010 (Expected) PhD
Department of Mining and Materials Engineering
McGill University, Montreal, Quebec

Thesis Title: Evolution of Microstructure and Texture in Twin-Roll Cast (TRC) Magnesium Sheet
The objective of this study is to investigate the microstructure and texture evolution in twin roll cast Mg sheet alloy AZ31,and developing new alloys for TRC (such as Mg-Mn-Ce,). Experimental techniques such as thermal analysis, optical microscope, SEM, EDS, EPMA, EBSD and X-ray Diffraction is used for microstructural and texture characterization. In order to understand the effect of cooling rate and alloying element on microstructure and texture of Mg alloys, prior to major project some minor project was conducted such as studying the effect of cooling rate on Microstructure of AZ31 magnesium alloy. Moreover the microstructure and texture of some of Mg Alloys such as Mg-Mn-Ce in as-cast, rolled and rolled/annealed has been studied.

2006 Master of Applied Science
Department of Materials Engineering
University of Windsor, Windsor, Ontario, Canada

Thesis Title: "Effects of Pressure levels and Calcium contents on the Microstructure and Tensile Properties of Squeeze Cast Magnesium Alloy AM50"

Squeeze casting, is a process by which molten metal solidifies under pressure within closed dies. The applied pressure produces a rapid heat transfer condition that yields a pore-free fine-grain casting with mechanical properties approaching those of a wrought product. Research work on development of squeeze casting of creep-resistant magnesium alloys is vacant. Moreover the process parameters have not been optimized for Mg alloys. Therefore the objective of this project was to develop an advanced process, which is capable of squeeze casting creep-resistant magnesium alloys for potential high-temperature automotive applications. Experimental techniques such as optical microscope, SEM, EDS, EPMA, tensile test were used for this study.
1997 Master of Science (Materials Engineering)
Department of Materials and Metallurgical Engineering
Iran University of Science and Technology, Tehran, Iran

Thesis Title: "Effect of Gating Design on Mold Filling of Aluminum alloy A413"
Gating system design is one of the most important factors in casting design. It affects the quality of castings by controlling the mould filling pattern and melt entry velocity. In this study, the effect of gating design including gate geometry and size on the flow pattern and melt entry velocity was investigated. This was achieved by pouring molten metal of aluminum alloy A413 into a sand mould. Different flow patterns were recorded by a video camera, and further analyzed by with direct observation and a computerized system. The experimental results indicated that the gating system ratio, geometry and size of the gate have a significant influence on the mould filling pattern and melt entry velocity.


1994 Bachelor of Science-Honor
