Additive friction stir deposition of AZ31B magnesium alloy

The current work explored additive friction stir deposition of AZ31B magnesium alloy with the aid MELD® technology. bar stock was fed through a hollow tool rotating at constant velocity 400 rpm and translating linear varied from 4.2 to 6.3 mm/s. A single wall consisting five layers each layer 140×40×1 mm3 dimensions deposited under processing condition. Microstructure, phase, crystallographic texture evolutions as function parameters were studied scanning electron microscopy including back scatter diffraction X-ray diffraction. Both feed material additively produced samples consisted ?-Mg phase. exhibited refined grain structure compared material. appeared have weak basal texture, while experienced strengthening this texture. showed marginally higher hardness provided pathway for solid state manufacturing Mg suitable structural applications such automotive components consumable biomedical implants.
