Fig.2 OM images of samples S1 (a1-a3), S2 (b1-b3), S3 (c1-c3), and S4 (d1-d3) (The as-cast sample served as the reference specimen without any subsequent treatment, labeled as S1. The bimetallic laminated composite directly annealed at 450 oC was labeled as S2. The bimetallic laminated composite subjected to cold rolling with the 70% reduction ratio followed by annealing at 450 oC was labeled as S3. To elucidate the strengthening mechanism of rolling + annealing more clearly, the bimetallic laminated composite with only 70% cold rolling was included as an additional control group, labeled as S4) (a1-d1) Cu-Ni-Si alloy sides (a2-d2) interface regions (a3-d3) 1010 steel sides
