英文摘要Adiabatic shear bands (ASBs) were studied by SEM electron channeling contrast (ECC) technique, which formed in fatigued copper single crystals with different orientations under high velocity impact using split-Hopkinson pressure bar (SHPB). The experimental results show that the critical strain of ASBs' formation is orientation-dependent. Single crystal close to the compression critical double slip orientation needs less strain for ASB formation than the crystals with typically single slip and close to compression conjugate double slip orientations. Single crystal close to the coplanar double slip orientation needs the maximum critical strain. Under current experimental circumstance the typical dislocation pattern within ASBs is dislocation cell structure, and no recrystallization was observed. There are three types of ASBs according to their orientations. The first type is that the plane of ASB is very close to the habit plane of the second type deformation band (DBII) in fatigued copper single crystals, which needs the minimum critical strain to form. The second type is rather close to the habit plane of either DBI (the first type deformation band) or DBII, which needs a modest critical strain. The third type is neither close to the habit plane of DBI nor DBII, which needs a the maximum critical stain.
