摘要：

After melting a FeCr12 alloy by CO2 laser, various zones are obtained: heat affected zone, melted zone and base alloy. Analytical studies (by Auger spectrometry) show that the segregation and diffusion of sulfur, during later annealing, are increased at the level of the laser treated zones (with a transition temperature towards 520-degrees-C). In the same way, evolutions in nitrogen content, going as far as precipitation, are shown. Interpretations take into account the structure evolutions after laser treatment and/or during segregation annealing.
