="ChDivSummary" name="ChDivSummary">A new parameter, i.e., tearing toughness, was employed to characterize the mechanical properties of some ductile metals(Cu, Cu–2 wt% Be, Cu–Al alloys, and some steels... and microstructures. It can be inferred that the tearing toughness of different ductile metals has their respective variation range, expectantly, and may be represented by the comprehensive mechanical......
