Microlevel Modeling of Thermophysical and Hydrodynamic Processes of Selective Laser Melting

A modified microlevel model, which is used to perform the numerical modeling of the double passage of a laser spot over a layer of metallic powder, is considered. As a result of the computational experiment, the temperature field is obtained and the edge effects are revealed. The microlevel modeling...

More Information
Summary:A modified microlevel model, which is used to perform the numerical modeling of the double passage of a laser spot over a layer of metallic powder, is considered. As a result of the computational experiment, the temperature field is obtained and the edge effects are revealed. The microlevel modeling allows determining the modes of melting and their applicability limits.
