Rolling equipment is roughly divided into three kinds; namely, hot rolling mills, cold rolling mills, and foil mills. Usually, rolling is performed by applying a load to the materials by forcing them vertically through a pair of work rolls. The work rolls are deformed by the high load during the rolling process.

Before hot rolling, the samples were heated up to 560 C in an electric furnace, with subsequent holding for 30 s at this temperature. To control the temperature during heating, rolling and quenching, a thermocouple was positioned in a hole drilled into the front face of each sample. After heating, samples were transferred from the furnace to the

ing that precedes hot rolling allows key elem-ents such as magnesium to diffuse from the bulk to the surface. Very different oxide structures can form during several hours in a furnace, and a further level of complex data fitting is required to optimize the pyrometers for extended hot formed oxide layers of dif-ferent base alloys.
