A ring-jig additive friction stir deposition method for efficient additive manufacturing of metal laminates. [PDF]

Nat Commun
Metal additive manufacturing (AM) has attracted attention for producing high-mix, low-volume, meter-scale components, especially for industrial applications. However, conventional AM requires high-energy input, expensive powders, and long processing times, limiting scalability and cost-effectiveness. To overcome these challenges, solid-state AM methods

The Role of Ultra‐Thin Passive Films and Organic Adsorbates on Aluminum Chips for a Friction‐Induced Solid‐State Recycling Process

Advanced Engineering Materials, EarlyView.
Despite benefits to storage stability and handleability of aluminum scrap, octadecyl phosphonic acid (ODPA) SAMs reduce the tensile strength of wires produced using friction‐induced recycling. Etching and methyl diphosphonic acid (MDPA) coatings, however, have little effect.
