Abstract In this study, parent aluminum (Al), silicon carbide (SiC) reinforced Al, zirconia (ZrO2) coated SiC reinforced Al, and lithium zirconate spinel (Li2ZrO3, LZO) encapsulated SiC incorporated Al metal matrix composites were processed via friction stir processing (FSP) technique to observe the influence of grain refinement on mechanical and damping properties. Electron backscattered diffraction (EBSD) analysis were conducted for detailed and deep understanding of possible mechanism and microstructure at longitudinal cross sections of the samples. Further, the room temperature mechanical properties and thermal cyclic (−100 to 400 °C) damping performance of the friction stir processed composites were studied. The results obtained in this investigation show that storage modulus of pristine Al, SiC reinforced Al, ZrO2 coated SiC reinforced Al, and LZO coated SiC reinforced Al were improved by a factor of 1.09, 1.17, 1.09, and 1.38, respectively, after FSP. Additionally, the ultimate tensile strength (UTS) and hardness of the friction stir processed SiC/Li2ZrO3/Al composite were improved by a factor of 1.08 and 1.11, respectively, after FSP was compared with an unprocessed composite.

The presented study deals with the investigation of biocompatible WE 43 Mg-based alloy processed via the combination of rotary swaging (RS) and friction stir processing (FSP) at three different rotational speeds of 400 RPM, 800 RPM, and 1200 RPM. The structure observations primarily focused on texture development and characterizations of grain sizes and grain boundaries. The results showed that swaging plus processing at 400 RPM and 1200 RPM lead to substantial recrystallization and grain refinement. The fractions of low angle grain boundaries within the 400 RPM and 1200 RPM samples were approximately 11%, while for the 800 RPM sample exhibiting secondary recrystallization it was about 22%. The grains were also the finest in the 1200 RPM sample (average grain diameter of 1.8 µm). The processed structures exhibited a slight tendency to form the {10-10} <0001> preferential fiber texture (especially the 800 RPM sample). Tensile testing showed the FSP to have positive influence on the ultimate tensile stress, as well as ductility of all the samples; the mechanical properties improved with increasing FSP rate.
