Assessing intermetallic growth characteristics in aluminum-to-steel welds

December 21, 2020

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 evaluating IMC formation has been developed by EWI Senior Engineer Michael Eff and is discussed in Design and Development of Resistance-based Rapid Thermal Cycle Diffusion Couples. This paper can be viewed at no charge by completing the form on this page.
