The relationship between shear band formation and crystallographic texture in rolled Cu-Ni-Co-Si alloy during bending was investigated. Shear band formation tendency was evaluated using SEM-EBSD and Taylor factors, and a prediction map was developed. The results provide a guideline for bendability evaluation.
