| Abstract | This paper studies a novel Al-Zn-Mg-Cu-Mn-Sc-Zr alloy that exhibits outstanding quenching sensitivity with a quench-hardening depth of more than 150 mm. Jominy end quenching allows the alloy to obtain different quenching rates. The Brinell hardness of the aged alloy with a quenching rate of 27 degrees C/s is 154 HB; when the quenching rate drops to 1.5 degrees C/s, its hardness value loses about 8%, which is 142 HB. The quenching-induced equilibrium precipitates heterogeneously precipitated at the grain boundary and the incoherent phase interfaces (E phase, Al-6(Mn, Fe) phase), but no heterogeneous precipitates are observed along the coherent L1(2)-Al-3(Sc, Zr) particles. After artificial aging, densely distributed nano-scaled atomic clusters and G.P zones, as well as grain boundary precipitation free zones (PFZs) were observed. |
