Synergy of Ni micro-alloying and thermomechanical processing in Al–Mg–Si–Cu–Zn–Fe–Mn alloys with enhanced bendability

Synergy of Ni micro-alloying and thermomechanical processing on the phase distribution, formability and bendability of Al–Mg–Si–Cu–Zn–Fe–Mn alloys was systematically studied in this paper. With the addition of micro-alloying Ni, the Ni-containing Fe-rich phase can be formed, which not only serves as...
