The effect of solute segregation at deformation twin boundaries on the strength (hardness) and damping capacity was investigated using an extruded Mg-Y binary alloy. The existence of deformation twin brought about an increase in both the hardness and

The damping capacity and mechanical response under uniaxial tension and compression were examined for specimens of extruded magnesium inclined by 0°, 15° and 30° relative to the extrusion direction. It was found that both the microyielding under u

The texture and tensile properties of a fine-grained Mg–Al–Zn alloy sheet at room temperature prior to and following superplastic deformation were examined. The pre-existing basal texture of the sheet drastically weakened after superplastic defor

Dislocation creep behavior of AZ31 magnesium alloy with different texture and grain sizes was examined. At a strain rate of around 10−3 s−1, it is suggested that the flow stress is dominated by the texture softening and softening due to grain bou

Dynamic elastic properties and damping properties from room temperature to 673 K were examined in AZ31 magnesium alloy. It was suggested that these properties at elevated temperatures were influenced by the occurrence of grain boundary sliding, which

Diffusion bonding behavior of fine-grained magnesium alloy with the average grain size of 8.5 μm, that was processed by hot rolling, was examined. The material behaved in a superplastic manner at temperatures of 523 and 573 K, and successfully diffu

Fine-grained ZK60 magnesium alloy with the grain size of 1.4 μm was processed by equal-channel-angular extrusion. The material exhibited low temperature superplasticity. The normalized plot suggested that the present material had equilibrium grain b

In the present study, superplastic behavior of a pseudo single phase magnesium alloy, ZK61, was investigated at about half the absolute melting point. The material was produced by the P/M route, and had a fine grain size of [approximately]500 nm. It
