Twin transmission across grain boundaries has important influence on deformation and fracture in hexagonal close-packed metals. Here, experimental and computational statistical analyses show that whether twins cross grain boundaries depends not only on crystal misorientation but also strongly on anisotropy in crystallographic slip.
