Summary: In this study, CoCrFeCuTi High Entropy Alloys (HEA) powder was reinforced on an SS304 steel substrate using a Friction Stir Processing (FSP) approach to achieve grain size refinement and improvement in mechanical properties. The microstructural analysis showed better grain refinement and dispersion of HEA reinforcement in the processed substrate. The Vickers microhardness and tensile strength were improved and the FSP-processed substrate with HEA also exhibited better resistance to corrosion.

Summary: This study investigates the microstructure and tensile properties of Mg-0.5Zn-0.2Si-XZr (X: 0, 0.25, 0.5 wt.%) under different processing conditions. Micro addition of Zr element can reduce grain size, but it is affected by Si poisoning effect. Processing the Zr-free alloy can improve its microstructure and mechanical properties. Further improvement in microstructure and mechanical properties can be achieved by multiple-pass FSP treatment of Zr-modified alloys.

Summary: The strength and ductility of nitrogen-alloyed CoCrFeMnNi high-entropy alloys (HEAs) were synergistically enhanced by multi-pass friction stir processing (FSP), resulting in refinement of the processed zone and a decrease in average grain size (AGS) with each FSP pass. Nitrogen-alloyed CoCrFeMnNi HEAs also exhibited a higher fraction of low angle boundaries (LABs) after FSP. The interaction between nitrogen atoms and LABs during FSP was indirectly proved by comparing the microstructural thermal-stability between different HEAs groups.

Summary: In this study, friction stir processing (FSP) was used to process a high-strength and high-melting-point Ni-Co based superalloy, achieving enhanced strength and ductility. The FSP samples exhibited significantly higher yield strength and ultimate tensile strength at both room temperature and 400 degrees C, demonstrating a synergy between strength and ductility. The mechanisms contributing to the improved mechanical properties, such as grain-boundary and nanotwin strengthening, were investigated and discussed.

Summary: The study investigated the electrochemical properties and microstructural evolution of FSPed HEA, and found that the formation of Cr2O3 passive layer enhanced the corrosion resistance of the alloy. Grain refinement in the stir zone facilitated the rapid formation of the passive layer, leading to better corrosion properties on the front surface. The micro-galvanic nature of HEA may contribute to the localized corrosion behavior observed.

Summary: The present study aims to enhance the mechanical properties of hypereutectic aluminium-silicon castings by modifying the microstructure and reducing defects through friction stir processing (FSP). By altering the tool revolution and the number of FSP passes, the study identified the specimen with the highest number of passes to have the most uniform properties, resulting from reduced casting porosities and refined silicon particle distribution in the friction stir processed zone.

Summary: In this study, a new biodegradable Mg-Zn-Cu magnesium alloy was introduced for biological applications. Addition of 0.1wt.% Cu was found to enhance corrosion resistance, with extruded alloys displaying better corrosion resistance behavior compared to cast alloys. The Mg-2Zn-0.1Cu alloy was identified as a potential candidate for use as a biodegradable magnesium implant due to its improved tensile properties.

Summary: The biocompatibility and biodegradation of iron make it suitable for developing biodegradable metallic implants. Incorporating gold into iron at low concentrations can improve its degradation rate. The Au-incorporated samples showed a significantly faster degradation rate and increased bioactivity compared to pure iron. Integrating nanogold into a Fe matrix promoted the formation of hydroxyapatite and did not cause toxicity to cells.
