Flash annealing

Normalization is an annealing process applied to ferrous alloys to give the material a uniform fine-grained structure and to avoid excess softening in steel. It involves heating the steel to 20–50 °C above its upper critical point, soaking it for a short period at that temperature and then allowing it to cool in air. Heating the steel just above its upper critical point creates austenitic grains (much sm… WebComparison of simulated temperature profiles between long dwell laser and flash annealing. Tpk = 1200°C, dwell time = 10ms, preheat T = 800°C for flash. Inset shows details magnified around peak temperature. LSA technology uses a long wavelength p-polarized CO2 laser with Brewster angle incidence.
