Finite element simulation on residual stress during immersion quenching and pre-stretching of Al7055 thick plates

Abstract During the immersion quenching process, severe temperature changes and significant differences between core superficial area can give rise to high residual stresses within aluminum alloy thick plate cause subsequent machining distortion of thin-walled part. Reducing stress effectively minimize in In this research, ABAQUS software was adopted simulate internal fields plates Al7055 during pre-stretching processes, sequentially respectively. addition, x-ray measurement method used measure characterize surface plates. The results indicate that medium affects inside significantly process. level which gradually increases as decreases. Further, treatment reduce plate, decreases with ratio increasing. experimental verify feasibility numerical simulation predict status Subsequently, a study for material removal processes carried out based on above studies. reveal part’s degree improves raw plate’s initial quench
