How can you control or compensate for springback in stamped parts when using new, advanced high-strength sheet metals? EWI has recently developed a specialized tool that is capable of assessing springback behavior without any wrinkling or necking on the tested part. The work is described in S-rail Test Tool for Evaluating Springback with High-strength Aluminum...

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...

Cold spray is one of the fastest metal additive manufacturing (AM) production techniques in the world. It offers an effective method for applying unique coatings and making repairs with similar or dissimilar metals. It eliminates heat affected zones and can be used on heat sensitive materials. It is an environmentally friendly process, particularly when compared...
