Morphological Development of Sub-Grain Cellular/Bands Microstructures in Selective Laser Melting

Morphological Development of Sub-Grain Cellular/Bands Microstructures in Selective Laser Melting

In this paper, single-layer and bulk 316 L selective laser melting (SLM) experiments were conducted, fine submicron-scale geometric symmetrical cellular (hexagonal, pentagonal and square), elongated cellular and bands solidification morphologies were found in the laser-melt top surface. Meanwhile, m...
