Evaluation of intermetallic compound layer at aluminum/steel interface joined by friction stir scribe technology

Evaluation of intermetallic compound layer at aluminum/steel interface joined by friction stir scribe technology

Heat input and high strain rate deformation during friction stir welding of aluminum and steel resulted in the diffusion-based formation of a FexAly intermetallic compound (IMC) layer. Compared with conventional friction stir welding tools, a friction stir scribe tool can reduce heat input significa...
