Fabrication of Magnesium–NiTi<sub>p</sub> Composites via Friction Stir Processing: Effect of Tool Profile
In this study, a solid-state fabrication route via friction stir processing (FSP) was used to fabricate Nitinol particulate (NiTi<sub>p</sub>)-reinforced magnesium-based composites to avoid the diffusion reaction and the formation of brittle interfacial compounds. The effect of four tool...

| description | In this study, a solid-state fabrication route via friction stir processing (FSP) was used to fabricate Nitinol particulate (NiTi<sub>p</sub>)-reinforced magnesium-based composites to avoid the diffusion reaction and the formation of brittle interfacial compounds. The effect of four tool profiles on the homogeneity in the dispersion of NiTi<sub>p</sub> particles in the magnesium matrix and microhardness was examined and analyzed. A counter-clockwise scrolled shoulder with a plain cylindrical pin and three tools with a flat shoulder having plain cylindrical pin, left-hand, and right-hand threaded pins were used and compared. The tool profiles were observed to exhibit a significant influence on the microstructure of the fabricated Mg/NiTi<sub>p</sub> composites. A wider and more uniform distribution of NiTi<sub>p</sub> particles along with superior bonding with magnesium matrix was achieved with a left-hand threaded cylindrical pin tool. The incorporation of NiTi<sub>p</sub> gave rise to a significant increase in the microhardness of the fabricated composites due to a variety of strengthening mechanisms. |
