Evaluation of temperature fields in corrosion-resistant steels under the action of laser radiation

We construct a mathematical model for the theoretical investigation of nonstationary three-dimensional temperature fields in bodies with plane boundary surfaces subjected to the surface laser treatment. The model takes into account the local character and the mode of action of laser beams, the shape...

Description
Summary:We construct a mathematical model for the theoretical investigation of nonstationary three-dimensional temperature fields in bodies with plane boundary surfaces subjected to the surface laser treatment. The model takes into account the local character and the mode of action of laser beams, the shape of the spot of heating, the path of its translational motion, the sizes of a product, and its heat exchange with the ambient medium. A procedure aimed at the prediction of the modes of laser treatment is proposed.
