Abstract:Fe-3%Si alloy single crystals were deformed in tension along the [110] or [001] axis at 77K and 298K in order to study the necking behavior. Two types of deformation band, kink band and band of secondary slip were formed on necking section of specimens deformed at 298K along the [110] or [001] axis, respectively. Cell structure of dislocations in deformed single crystals appeared on the necking section in both axes. Such dislocation structure is supposed to influence non uniform deformation of the crystals.

Key Words:non-uniform deformation, necking, slip system, deformation band, cell structure of dislocation
