The process uses neither lasers nor electron beams. Friction between a specialized tool and the workpiece heats aluminum into a plastic state for layerwise deposition. The team says the resulting fine-grained structure is stronger than cast and forged parts, with printing 1.5 times faster than wire arc additive manufacturing, WAAM. Previously, only the United States and China had mastered solid-state metal additive technology globally.
Project leader Oleg Panchenko explained that conventional melting creates pores, hot cracks, and residual stresses, which the solid-state route avoids. The team plans to extend the process to welding and repair of copper, nickel, and other metals. Russia's Priority 2030 federal program supports the project.
Nanjixiong's Observations
Solid-state friction-based additive manufacturing has inherent advantages for aluminum repair and large structural components. Without a liquid phase, melt-pool defects do not arise.
