Thesis Title: Elevated Temperature Mechanical Properties of Line Pipe Steels

 Abstract: The effects of elevated temperature (25-400 °C) on the tensile properties of X70 and X52 steels are under evaluation. Dynamic strain aging (DSA) is a strengthening mechanism active in steel systems in the temperature range of interest and results in non-uniform deformation (i.e. serrated yielding in the flow curve), increased strength, reduced ductility, and negative strain rate sensitivity. The mechanical properties are evaluated using elevated temperature tensile testing, digital imaging correlation, and internal friction. Microstructures are evaluated before and after plastic deformation at elevated temperatures using x-ray diffraction, synchrotron x-ray diffraction, scanning electron microscopy, and transmission electron microscopy.
