in 438-215 ℃ interval is the primary factor that affects the hardenability of this alloy during the quenching. The equilibrium state MgZn2 phases precipitate as two paths successively during the quenching: grain boundaries and inside the grains, with the peak temperature 387 ℃ and 342 ℃ respectively. Key word: Al-Zn-Mg-Cu; end-quench test; hardenability; equilibrium MgZn2 phase 在航空航天工业迅速发展的今天,整体结构件的应用可以......

at grain boundaries are TiC+Ti3AlC dual phase structure. The core particle is TiC and the interfacial transition zone is Ti3AlC existing between TiC particle and α+γ matrix. Ti3AlC is in equilibrium with α2-Ti3Al and γ-TiAl when the alloy was annealed at 900℃, while Ti3AlC reaches equilibrium with α-Ti and γ-TiAl at 1250℃. In α2+γ phase field, TiC+Ti3AlC dual phase structure particles in as cast alloy......
