金属学报(英文版)

The microstructure of 7050 AI alloy in T74 condition has been studied by means of transmis- sion electron microscopy and dynamical diffraction simulation.It was found that the alloy studied contains mainly AI3Zr superlattice phase,η′-phase and Al_7Cu_2Fe constituent phase. The η′-phase has an orthorombic crystal structure with a=0.492 nm,b=0.852 nm and c=0.701 nm.The orientation relationship between the η′-phase and matrix was determined as(101)_m∥(010)_(η′)[111]_m∥[001]_(η′)
