Thermal behavior and densification mechanism during selective laser melting of copper matrix composites: Simulation and experiments (2014, background): “Assuming that the particles are spheres and there is no flattening of contact surfaces, the effective thermal conductivity of the powder bed, j, is estimated by [29]:”
Process parameter selection for selective laser melting of Ti6Al4V based on temperature distribution simulation and experimental sintering (2012, background): “[19–21] provided the finite element analysis of volume shrinkage during the process of laser densification, which led to two kinds of guidelines to determine the phase transition temperature of the powder.”
