| Abstract Scope |
Friction Stir Welding (FSW) is a solid-state joining technique that utilizes non-consumable tool to stir two materials into a joint. In this study FSW parameters were developed and used to weld Wrought Homogeneous Armor steel. Metallography, micro hardness indention, and thermal modeling was also employed to predict the joint’s properties. Through this work parameters were down-selected to make defect free weld. Examining the micrographs and SEM images, the microstructure appeared to be fully martensitic. The martensite found in the stir zone (SZ) and heat affected zone has undergone auto-tempering as well. When examining the micro hardness profile of the weld, it appears that the SZ hardness is close to that of the base metal. This would indicate that some level of tempering is occurring during the welding process, leaving a tempered martensitic microstructure. |
