| description | In the presented work, the effect of friction stir processing admixing the zirconium tungstate ZrW<sub>2</sub>O<sub>8</sub> powder on the microstructure, mechanical and tribological properties of the AA5056 Al-Mg alloy stir zone has been studied. The FSP resulted in obtaining dense composite stir zones where α-ZrW<sub>2</sub>O<sub>8</sub> underwent the following changes: (i) high-temperature transformation into metastable β’-ZrW<sub>2</sub>O<sub>8</sub> and (ii) decomposition into WO<sub>3</sub> and ZrO<sub>2</sub> oxides followed by the formation of intermetallic compounds WAl<sub>12</sub> and ZrA<sub>l3</sub>. These precipitates served as reinforcing phases to improve mechanical and tribological characteristics of the obtained fine-grained composites. The reduced values of wear rate and friction coefficient are due to the combined action the Hall–Petch mechanism and reinforcement by the decomposition products, including Al<sub>2</sub>O<sub>3</sub>, ZrO<sub>2</sub>, β’-ZrW<sub>2</sub>O<sub>8</sub> and intermetallic compounds such as WAl<sub>12</sub> and ZrAl<sub>3</sub>. Potential applications of the above-discussed composites maybe related to their improved tribological characteristics, for example in aerospace and vehicle-building industries. |
