HIGH TEMPERATURE AND HIGH STRAIN RATE SUPERPLASTIC DEEP DRAWING PROCESS FOR AA5049 ALLOY CYLINDRICAL CUPS
Journal Title: International Journal of Engineering Sciences & Research Technology - Year 0, Vol 5, Issue 2
Abstract
In this present work, the formability of high temperature and high strain rate deep drawing process were estimated for the cylindrical cups using Taguchi technique and finite element analysis. The process parameters were temperature, strain rate, coefficient of friction and blank holder velocity. The formability limit diagrams were developed for all the trials. The AA5049 alloy sheets were used for the deep drawing of the cylindrical cups. The formability of the cups was excellent for the temperature of 500oC and strain rate of 10 s-1 .
