| Abstract | The purpose of this study was to discuss the change in microstructures and hardness values in fusion zone (FZ) and heat-affected zone (HAZ) of austenitic stainless steel and carbon steel welds. By comparison, the morphology of δ – Ferrite which formed in the fusion zone of single-pass and multi-pass welding was analyzed. The columnar dendritic shape can be seen as features extending from the fusion line of a weld pass toward the subsequent passes. Furthermore, the δ-Ferrite morphology changed from fine cellular to columnar dendrite or equiaxed dendrite. The recrystallization phenomenon was only observed in the HAZ carbon steel side of multi-pass welding. This zone was divided into HAZ-1 (grain-refining region) and HAZ-2 (partial grain-refining region). The hardness values in each zone were measured with the highest value was on fusion boundary of carbon steel side. Transverse tensile was carried out. |
