Structure and Properties of Grain Boundaries in Submicrocrystalline W Obtained by Severe Plastic Deformation

Abstract:

Article Preview

Submicrocrystalline structure of W obtained by severe plastic deformation (SPD) by high pressure torsion (5 revolutions of anvils at 4000C) and its thermal stability have been examined by TEM. Grain boundaries of submicrocrystalline W have been studied by the method of the emission Mössbauer spectroscopy in the initial state and after annealing at 400-6000С.
