摘要：
PROBLEM TO BE SOLVED: To provide an alloy and a formed article which have excellent mechanical strength, ductility and impact resistance, and have no anisotropy in mechanical properties.
SOLUTION: In the method of producing an extrusion material, the crystal grain size and texture thereof are controlled by dynamic recovery and/or dynamic recrystallization in plastic working. A stage where shear stress is applied to an alloy stock in such a manner that the extruding direction is changed by the internal angle of
