## Description

- description: 'Effect of twin boundary with/without segregation on deformation behavior
    in tension is examined using Mg-3Al-1Zn (AZ31) alloys from quasi-static strain
    rates to high strain rates.  Solute atoms are segregated at{10\bar{1}2}{10&#1macr;2}
    twin boundaries by static annealing at a temperature of 423 K with a holding time
    of 150 min.  The room-temperature tensile mechanical response of the alloys, which
    have pre-induced twin boundaries, shows detwinning behavior, regardless of the
    strain rate between 10-4 /s and 100 /s.  The yield strength of these alloys is
    also unlikely to be affected by strain rate, because twin boundary mobility, i.e.,
    shrinkage, is an athermal process.  On the other hand, the alloy with segregated
    twin boundaries exhibits an increased strength and a decreased strain hardening
    compared with those in the alloy with non-segregated twin boundaries.  Newly formed
    deformation twins of several types, i.e., the {10\bar{1}2} twins, {10\bar{1}1}
    twins and {10\bar{1}2}-{10\bar{1}1} double twins, are the origin of fracture in
    these alloys.  '
