Shear ban.s in.metallic materials have been.reported to be catastrophic because they n.rmally lead to n.n.un.form plastic deformation. Ductility of lamin.ted metallic composites deteriorates with in.reasin. processin. strain. particularly for those havin. hexagon.l-close-packed(hcp) con.tituen.s due to in.dequate slip systems an. con.equen.ly promin.n. shear ban.in.. Here, we propose a design.strategy that coun.erin.uitively tolerates the ban.s with localized strain., i.e. the shear ban.ed lamin.r(SBL) structure, which promotes dislocation.activation.in.hcp metals an. ren.ers un.receden.ed stren.thductility combin.tion.in.hcp-metal-based composites fabricated by accumulative roll bon.in.(ARB). The SBL structure is characterized with on. soft hcp metal con.train.d by adjacen. hard metal in.which dislocation. have been.accumulated n.ar the bimetal in.erfaces. High-en.rgy X-ray diffraction.aston.shin.ly reveals that more than.90% of dislocation. are n.n.basal in.Ti layers of the SBL Ti/n. composite processed by eight ARB cycles. Moreover, dislocation. occupy a high fraction.of ~30%, promotin. further cross slip. The un.que stress field tailored by both shear ban.in. an. heterophase in.erface-mediated deformation.accommodation.triggers importan. slip. This SBL design.is of sign.fican.e for developin. hcp-based lamin.tes an. other heterostructured materials with high performan.es.
