چکیده انگلیسی
Plastic anisotropy of the as-rolled 7050 aluminum alloy plate was investigated by tensile tests conducted at different temperatures (340 and 460 °C) and different strain rates of 1.0 Ã 10â4, 1.0 Ã 10â2, 0.1, and 1 sâ1. The results show that the plastic strain ratio of the as-rolled 7050 aluminum alloy plate deformed at 340 °C is not sensitive to strain rate, which increases with increasing strain rate when the alloy was deformed at 460 °C. Alloy elements of the alloy deformed at 460 °C and different strain rates are in solution. The plastic strain ratio of the alloy deformed at 460 °C was affected by texture components, especially the Brass orientation {0 1 1}ã2 1 1ã. Dynamic precipitation appears when the alloy was deformed at 340 °C and different strain rates, and the alloy deformed is in over aged condition. Microstructure is the main influence of plastic anisotropy of the alloy deformed at 340 °C.
