Low plane-strain deformation enhances the hardness by refining microstructure and introducing dislocations.
Nano-indentation, during which a small tip deforms a crystalline film, is a common tool for introducing dislocations into a small volume that is initially defect-free3,4,5,6,7,8,9,10.
Radiation damage degrades the efficiency with which charge is transferred in the CCD by introducing dislocations in the semiconductor which trap electrons and prevent their transfer.
In this case, the system lowers its total free energy by introducing dislocations.
Nanoindentation is an ideal technique for studying the fundamental behaviors and properties of dislocations in a crystal by introducing dislocations into a small volume that is initially defect-free.
However, with extension of deposition time, more Mn atoms are supplied, and this will introduce dislocations in the NWs [9, 27, 28], resulting in the fragmentation of NWs and, finally, the reduction in their lengths.
Pure Fe and Fe 1.4Mn alloy were irradiated with Fe3+ ions to introduce dislocation loops.
Strengthening in graphene/metal composite is limited to the intrinsic strength of graphene and its ability to block dislocation from propagation, which make it very difficult to introduce dislocation hardening and twin boundary strengthening.
The mixed boundary value problem is first reduced to a singular integral equation with a Cauchy type kernel in the Laplace domain by applying Laplace and Fourier integral transforms and introducing dislocation density function.
According to the R-T dislocation model, we introduce Volterra dislocations at x = ±a,y = h x,y and z coordinate axes are shown in Fig. 1) and the dislocations are in equilibrium.
