摘要: Using scanning transmission electron microscopy, we uncover the interaction between {10 (1) over bar3} twin and stacking faults (SFs) enriched with solute atoms in an Mg97Zn1Y2 alloy at atomic scale. The pyramidal-basal (PyB) and basal-pyramidal (BPy) interfaces along SFs make faceted {10 (1) over bar3} twin boundary deviate appreciably from {10 (1) over bar3} twin plane. {10 (1) over bar3} twin associated with shear can reorient one unit of SF, but engulf two successive SFs. {10 (1) over bar3}-{10 (1) over bar1} twin segment generated upon twin-SFs intersection region, and is proposed to arise from dislocation dissociation. The direct observations unravel some of the fundamental characteristics of interaction between compression twin and precipitates in magnesium alloys.
