Micro Structural Features Induced by Sheet Hydroforming ofNon- Ferrous Metals and Alloys by Forouhandeh F in Research & Development in Material Science
Sheet hydroforming process has
been used for near-net shape forming of non-ferrous metals and alloys. A
commercial purity Al, Cu and Ti metals as well as α-brass an alloy of Cu-Zn has
been formed into various shapes using an indigenously designed experimental
set-up. The process parameters have been selected based on the previous study
on simulation of this process. The process is shown to exhibit a better surface
quality of products together with relatively high drawing ratio. These effects
along with uniform distribution of stresses cause considerable reduction in
secondary processing of the component. The micro structural features of sheet
hydro-formed products are reported. The uniformity in grain size and grain size
distribution of all the materials employed in the present work are presented
and discussed. Important advantages of this method vis-à-vis conventional cup
drawing techniques are illustrated.
