Metal Composites

Michael Eff, EWI Congratulations to EWI Principal Engineer Michael Eff who has won (along with colleagues Logan Smith and Ian Donaldson) the 2022 Howard I. Sanderow Outstanding Technical Paper Award from The Metal Powder Industries Federation. The paper, Joining of Two-Piece Aluminum Metal Matrix Composite (Al-MMC) Transmission Carrier Via Friction Stir Welding, was selected from...

Metal matrix composites (MMCs) have always been considered “unweldable,” and have been joined mechanically in the past. Now, however, EWI reports that aluminum MMCs can be joined using friction stir welding, a solid-state joining method. This investigation is discussed in Friction Stir Welding of Metal Matrix Composites, written by EWI Senior Engineer Michael Eff. You...

Ultrasonic metal foil additive manufacturing is a technology that was pioneered by Fabrisonic, an affiliate of EWI. It uses ultrasonic welding to build up metal parts layer by layer – a low-temperature, solid-state process that can produce 3D-printed parts as large as 6’ x 6’ square. Recently, Fabrisonic President Mark Norfolk gave a terrific explanation...
