摘 要：Three types of laminates were designed by alternately stacking AZ91 extruded sheets in different states for extrusion to improve the mechanical *** tensile tests revealed that the combination of solid-solution-treated sheets with the aging-treated sheets achieved high tensile strength and ductility,i.e.,ultimate tensile strength of~386 MPa and elongation of~19.8%,*** backscatter diffraction(EBSD)and TEM results indicated that the aging-treated layers with more nano-sized precipitates and small grain size provided high strength and reasonable ductility,while the solid-solution-treated layers with low dislocation density facilitated strain ***,the strong interface bonding between the successive layers played an important role in the enhanced ductility.
