Abstract
⺠UFG materials produced by SPD do exhibit specific GBs defined earlier as “non-equilibrium GB”. ⺠Such boundaries differ from regular GBs on atomic structure and appearance of long-range stresses. ⺠The apparent thickness of “non-equilibrium” GB is typically in a range of 1 to 2 nm. ⺠GBs in SPD materials may promote segregations and mechanical mixing that affect the properties. ⺠“Non-equilibrium” GBs do significantly enhance the atomic mobility in SPD materials.
