Paragraph starter
The development of Additive Friction Extrusion Deposition (AFED) offers a significant advancement in producing high-strength nanocomposites. As demonstrated by Sun et al. (2025), AFED enables the fabrication of heat-treatment-free CNT/Al6Mg nanocomposites with a remarkable 78% increase in yield strength compared to conventional Al-Mg alloys, primarily due to enhanced grain boundary and Orowan strengthening mechanisms. This bypasses the distortion and cracking issues associated with traditional post-processing heat treatments, opening new possibilities for complex, high-performance metallic components.
