Investigation into the hot workability of the as-extruded WE43 magnesium alloy using processing map (original) (raw)

The research concerned the characterization of the hot-working behavior of the asextruded WE43 magnesium alloy potentially for biomedical applications and the construction of processing maps to guide the choice of forming process parameters. Isothermal uniaxial compression tests were performed over a temperature range of 350-480 1C and strain rate range of 0.001-10 s À 1 . Flow stresses obtained were used to construct processing maps. Domains in processing maps corresponding to relevant deformation mechanisms, i.e., dynamic recrystallization (DRX), dynamic recovery (DRV) and flow instability, were identified, according to power dissipation efficiency and flow instability parameter values.
