Microstructural characterization of laser formed high-strength-low-alloy (HSLA) steel

Kgomari, Lerato Criscelda. January 2010 (has links)
Thesis (MTech. : Engineering Metallurgy.)--Tshwane University of Technology, 2010. / Establish a qualitative and quantitative comparison between the parameters of the laser used in manufacturing a 120 mm curvature in HSLA steel parts and the micro-structural changes in the steel part. Subsequently, the final microstructure will be used to determine the reason for the poor fatigue performance of the HSLA steel after laser forming.
