文摘
- •
Evolution of microstructure and texture of ZK60 (Mg-5.5Zn-0.5Zr) was examined during deep drawing.
- •
Two different ZK60 alloys of ingot casted (IC) and twin-roll casted (TRC) were compared.
- •
Major deformation modes between the IC and TRC sheets were different during drawing process.
- •
Tensile twinning and shear bands were frequently observed in IC cups.
- •
Peak broadening along the TD and a peak split along the RD were more observed in TRC cups.
