Dilatant shear bands in solidifying metals

dilatancy, shear, granular media
The authors study the microstructure of partially solidified alloys under shear. It is found that these alloys behave similarly to a cohensionless granular material, exhibiting Reynold's dilatancy and strain localization in dilatant shear bands.
