Combining aluminum and steel construction in vehicle manufacturing can offer great lightweighting and strength advantages. The formation of brittle intermetallic compounds (IMCs) in the joints between the materials, however, are known to impair performance. Prediction of such intermetallic formation is often difficult to assess due to the rapid thermal cycles involved. A new technique for...

Low force friction welding, a hybrid technology developed by EWI and MTI, uses an external energy source to raise the interface temperature of the parts being welded, reducing process forces required to make a solid-state weld compared to traditional friction welding. Low Force Friction Welding of Bimetallics: Aluminum 6061 to 1020 Steel Tubes, written by...
