Abstract

In the present research the influences of manufacturing parameters e. g. laser scan rate and working atmosphere on densification and MICROSTRUCTURE of M2 HIGH-SPEED STEEL powder via direct metal LASER SINTERING (DMLS) were studied. Density and micro-hardness measurement experiments were performed on, produced specimens and microstructural evaluation was done with both optical and scanning electron microscopy (SEM). The result of experiments showed that the density of laser sintered specimens decreased linearly with increasing the laser scan rate. Furthermore, sintering under the argon atmosphere yields higher densification than the nitrogen atmosphere. It was found that laser sintered specimens have cellular and/or dendrite MICROSTRUCTURE due to rapid solidification during the DMLS process. Also, the size of pores is independent to laser scan rate, sintering atmosphere and chemical composition.
