Recently Lomer-Cottrell (L-C) locks as barriers to pin and entrap dislocations and thus to enhance work-hardening and ductility of nanostructured (NS) metals and alloys have received attention. This letter reports on a new type of L-C locks with multiple stair-rod dislocations, enabling them ...

During strain hardening stage, abundant Lomer-Cottrell (L-C) locks formed both within nanograins and against twin boundaries. Two major mechanisms were identified during interactions between L-C locks and twin boundaries. Quantitative nanoindentation experiments recorded show an increase of yield strength...

Misfit dislocations in the SiGe system are usually not dissociated. We present the first observation of a Lomer–Cottrell lock array in a Si/Si1xGex/Si heterostructure (0.4<x<0.6). We describe the character of the stacking faults and the partial dislocations which form the locks.关键词:German...
