Compression along the Easy-Glide Orientation of Ultrafine and Fine-Grained Mg-3Al-1Zn Alloy
2010
The deformation behavior of textured ultrafine-grained (UFG) and fine-grained (FG) Mg-3Al-1Zn alloy compressed along the easy-glide orientation was studied. It was found that severe strain localization within very thin shear bands (SBs) caused the loss of ductility in UFG Mg-3Al-1Zn alloy. Increasing grain size increases the width of SBs, which decreases the degree of strain localization. The reason for the occurrence of severe strain localization in textured UFG Mg-3Al-1Zn alloy is proposed.
