Effect of bright annealing on stainless steel 304 formability in tube hydroforming
TL;DR: In this paper, the effects of bright annealing (BA) on enhancing formability of stainless steel 304 tube in a tube hydroforming (THF) process were studied, and the results showed that BA alone failed to achieve desired tube expansion of the diameter of 50.8 mm.
