to the limited slip system at room temperature in HCP Mg alloys, twinning has been theoretically and experimentally proven to be the dominant model that is responsible for plastic deformation. Although several...: The twinning and slip activities of AZ31 magnesium alloy sheet at a strain rate of 1 200 s-1 were investigated. Dynamically mechanical properties of various oriented samples were measured using......
slip are demonstrated in Figures 11-13. The coordinate system was based on the hypothetical tunnel axis as the abscissa, the mid-point of the tunnel crossing the fault core as the origin, and vertically... of displacement of each fault sub-strips in total displacement over 100 years 7 Experimental study 7.1 Development of disk rotation test system and corresponding test method Creep slip of the active......
texture becomes stronger and stronger and the prismatic texture becomes weaker and weaker with increasing the strain. The prismatic texture is formed by the initiation of the prismatic slip system in the grains with particular orientations, the prismatic texture is weakened by <> twinning and static recrystallization twinning-induced during annealing. Key words: slip system; twinning; texture......

property depends on the interfacial slip between the inner particles and the matrix. Different from the general composite materials, the interfacial slip in MRE is affected by the external applied magnetic field. Key words: magnetorheological elastomers; damping property; interfacial slip 1 Introduction Magnetorheological elastomer (MRE) is a class of smart material whose rheological......
stress (CRSS) for twinning to ordinary slip, prism to twinning and pyramidal to prism can be described as k∶e∶z=1∶3∶18.
