Polygonization and plastic bending of whiskers induced by pulsed power electron beam

Dynamics of bending of NaCl whisker is studied with use of high speed camera VFU-1 synchronized with high power electron accelerator GIN-600. The dynamics of bending turns to be non-monotonous and quite complicated. The figures of etching of whisker after bombardment by electron beam are analysed, thin polygonization in samples is found. The time of bending in experiment and time of forming of dislocation walls computed on the base of theory of plastical bending are compared.
