Deformation process in real crystal structures

Dislocations provide low-stress deformation due to the gradual sliding of atomic blocks. https://youtu.be/54H5HQlMEio Introduction To initiate a deformation process, a certain critical resolved shear stress (CRSS) is required at the atomic level. As described in...

Deformation process in single crystals

Deformation in single crystals is divided into four stages: elastic, easy glide (single slip), multiple glide and recovery. https://youtu.be/meUF-9i-4Qw Introduction Even if single crystals are used far less than polycrystals, one can understand very well the processes...
