摘要：
Twinning of a polycrystalline Mg-3Al-0Mn alloy at a uniaxial tensile strain rate of 0.001 s(-1) to a total strain of 0.02 was studied by transmission electron microscope. The deformation of twins, necking and cracking, was observed. Meanwhile the interception of twins resulted in double twinning and slip along the double twin boundaries. Their effects are discussed in view of work hardening/softening of magnesium alloys. (C) 2014 Elsevier B.V. All rights reserved.
