Friction Stir Additive Manufacturing (FSAM) is an emerging technique in the field of additive manufacturing that applies the principle of friction stir welding for adding sheets as layer-by-layer fashion. This study aims to conduct a comparative analysis of the mechanical properties of AA6061-T6 components fabricated using single-track and multi-track FSAM. Single-track FSAM involves the deposition of material along a single path, while multi-track FSAM incorporates multiple overlapping tracks to build up the material. The primary focus is on evaluating how these two fabrication approaches influence the microstructure, hardness, tensile strength, and fractography analysis of the resultant AA6061-T6 specimens. By understanding the differences in mechanical properties between single-track and multi-track FSAM-fabricated AA6061-T6, this research seeks to provide insights into optimizing process parameters for enhanced performance. The findings will contribute to the broader knowledge base of additive manufacturing techniques, potentially guiding the development of more efficient and reliable manufacturing processes for high-performance aluminum alloys.

摘要

Friction Stir Additive Manufacturing (FSAM) is an emerging technique in the field of additive manufacturing that applies the principle of friction stir welding for adding sheets as layer-by-layer fashion. This study aims to conduct a comparative analysis of the mechanical properties of AA6061-T6 components fabricated using single-track and multi-track FSAM. Single-track FSAM involves the deposition of material along a single path, while multi-track FSAM incorporates multiple overlapping tracks to build up the material. The primary focus is on evaluating how these two fabrication approaches influence the microstructure, hardness, tensile strength, and fractography analysis of the resultant AA6061-T6 specimens. By understanding the differences in mechanical properties between single-track and multi-track FSAM-fabricated AA6061-T6, this research seeks to provide insights into optimizing process parameters for enhanced performance. The findings will contribute to the broader knowledge base of additive manufacturing techniques, potentially guiding the development of more efficient and reliable manufacturing processes for high-performance aluminum alloys.
