_Project_

This is a masters project (M.Sc.) in applied science. Polytechnique Montreal is an engineering school in Montreal, Canada.

This project concerns the manufacturing of sheet metal in continuous galvanizing lines. Rejection rates are high in processing of advanced high-strength steels (AHSS) because the mechanical properties of these steels are sensitive to temperature variations. Temperature estimates via pyrometry (based on surface emissivity) depend upon surface state. Consequently, it is difficult to estimate temperature based upon pyrometric readings from the steel’s surface as it evolved during treatment in the galvanizing line. Oxidation furthermore influences the adhesion of the zinc.

The purpose of this project is to study the influence of heating rate and cooling rate upon the microstructures and mechanical properties of these steels. The adhesion of the zinc will also be explored.

This project will subject AHSS steels to a variety of heat treatments. The milestones of the project are as follows:
1. Perform a literature review on thermodynamic and metallurgical theory on duplex steel phase transformations.
2. Propose and effect a series of dilatometry experiments. Perform optical and electronic metallography and mechanical testing. Nanoindentation will also be performed.
3. Perform a series of heat treatment tests in the galvanizing simulator at McMaster University.
4. Determine the effect of heating rate and cooling rate upon the zinc adhesion. Perform bending tests.
5. Expand the study to evaluate the effects of chemical composition.
6. Develop continous cooling transformation charts using CALPHAD software.

The masters student will collaborate with a postdoctoral fellow.
