摘要: Abstract In this paper static and dynamic strain ageing behavior in Al–Mg–Si alloys related to equal channel angular pressing (ECAP) was investigated. order examine the combined plastic deformation, solution treatment effects on strengthening characteristics, experimental results of without ECAP, pre-ECAP ageing, post-ECAP inside ECAP die were compared. particular, temperature, time, rate sequence heat Vickers hardness discussed. To achieve a higher hardness, an optimum cycle with process is presented based current study. By employing proposed schedule value increased from 86 HV (as-solution treatment) 138 (peak schedule).
