Numerical study of heat transfer and phase change in a single metal particle of powdermaterial in application to selective laser sintering.

Kurzbeschreibung (Abstract)

The heat transfer and phase change induced by interaction between a spherical metal particle and pulsed laser source during liquid-phase sintering of metal powders is investigated numerically. The heat transfer model used for this study accounts for melting and resolidification occurring during heating and cooling phases of pulsed laser sintering. The particle surroundings are modeled as a continuum representing the loose powder. Evolution of temperature field and the phase change in the metal particle as well as its surroundings are discussed. The influence of laser pulse frequency, pulse duration, and powder particle size on the melting process are described.
