MECHANICAL AND TRIBOLOGICAL STUDIES OF TI-6AL-4V BY FRICTION STIR PROCESSING

Mechanical Engineering

Friction stir processing (FSP) is a promising technique for improving the mechanical and tribological properties of materials. This study focuses on investigating the effects of FSP on Ti-6Al-4V, a widely used titanium alloy. Existing Ti-6Al-4V processing technology has limitations such as reduced strength and ductility in the heat-affected zone. The aim of this research is to evaluate the potential of FSP in improving the mechanical and tribological properties of Ti-6Al-4V. The methodology includes performing FSP on Ti-6Al-4V samples and analyzing the resulting microstructure and mechanical properties. Key findings indicate that FSP significantly refines the microstructure of Ti-6Al-4V, leading to improved mechanical properties, including increased strength and ductility. The discussion interprets these results and highlights the advantages of using FSP for Ti-6Al-4V. The conclusions highlight the positive results of this research and suggest that FSP can be an effective technique for improving the mechanical and tribological properties of Ti-6Al-4V. Keywords for this study include Ti-6Al-4V, frictional mixing, mechanical properties, tribological properties, microstructure refinement, strength and ductility. Overall, this study provides valuable insights into the potential of FSP as a means to improve the performance of Ti-6Al-4V and addresses the existing limitations of the current technology. These findings contribute to the advancement of materials processing techniques and have implications for various industries that use Ti-6Al-4V in their applications.
