A Modified Johnson–Cook Model and Microstructure Evolution of As-Extruded AA 2055 Alloy during Isothermal Compression

Isothermal compression behaviors of as-extruded AA 2055 alloy (T6 state) were studied at temperature of 320, 380, 440 and 500 °C with strain rate of 0.001, 0.01, 0.1 and 1 s<sup>−1</sup> by a Gleeble-3800 testing machine. A modified Johnson–Cook model fitted by polynomial and power-exponential funct...
