    LASER INDUCED STRUCTURAL TRANSFORMATION IN AISI 430 STEEL

    No full text
    AISI 430 steel plates have been irradiated with 2kW cw CO2 laser. Optical and transmission electron microscopy studies, revealed that the carbides existent before irradiation are dissolved in the irradiated zone where the steel was melted. After solidification, an uniform distribution of the ε - carbide precipitates, 50 - 100 nm in size, appeared. The precipitation process was connected with the diffusion at dislocation core and with dislocation displacements and multiplications
