Effect of the laser heat treatment on the formation of the gradient structures in alloys based on Fe – Cr – Ni system

Hierarchically patterned multiphase steels created by localised laser treatments

“…These studies demonstrate the suitability of using laser treatments to engineer the microstructure of alloys, although the use of this technology to develop pattern topologies with the potential to achieve unprecedented properties has been barely explored. Only very recently, Andreev et al [21] and Pimenov [22] developed gradient microstructures in a Fe-Cr-Ni metastable austenitic steel by reverting a cold-rolled martensitic microstructure by laser treatment using shadow masks of different geometries.…”
