An attempt was made to clarify the difference in behavior, during rolling, of low and very-low stacking fault energy face-centered cubic materials. The rolling textures of pure Ag and Ag-Zn solid-solution alloys which contained 8 or 18wt%Zn were investigated by means of X-ray texture, including calculations of the orientation distribution function, for a wide range of rolling reductions. For reductions in thickness of more than 95%, the final textures in all of the specimens of Ag and Ag-Zn alloys were almost similar. They exhibited the typical brass-type rolling texture in which mainly {110}<112> developed; together with the minor component, {110}<001>. For degrees of reduction of the order of 50 to 75%, the Ag-Zn alloys with very low stacking-fault energies behaved in a markedly different manner to that of Ag alloy with a moderately low value of stacking-fault energy. In the intermediate range of rolling reductions, the formation of the {111}<011>-type component - which was considered to be a distinct texture component of very-low stacking-fault energy alloys - was enhanced with increasing Zn content. This characteristic feature appeared in the rolling texture of very low stacking-fault energy alloys, and was considered to be associated with the so-called non-Wassermann effect of deformation twinning.
