. There are two kinds of softening mechanisms in thermal deformation process-dynamic recovery and dynamic recrystallization. Dynamic recrystallization occurs under the condition of high temperature and low strain... words: low carbon microalloyed steel; hot deformation; flow stress; dynamic recovery; dynamic recrystallization
to the coarsening of precipitates, drop of dislocation density, and increase of dynamic recovery. After tensile testing at 250 °C, a sub-grain structure composed of a high fraction of small-angle grain boundary is formed. Key words: Al-Zn-Mg-Cu alloy; dynamic recovery; high temperature mechanical properties; microstructure 1 Introduction Al-Zn-Mg-Cu alloys possess the advantages of high specific strength......模锻态Al-5.87Zn-2.07Mg-2.42Cu合金的高温力学性能和显微组织
