Influence of welding parameters on intermetallic compounds formation in dissimilar steel/aluminum friction stir welds

It is difficult to obtain a quality joining of steels to aluminum alloys by fusion welding processes due to the large difference between melting temperatures and the formation of thick brittle Al/Fe intermetallic compounds at the joint interface. In this study, lap welds between Al 1100 and St37 ste...
