Analysis of the Crystallographic Microtexture of a UNS S32205 and a UNS S32304 Duplex Stainless Steels After Cold Rolling and Heat Treatment

Samples of duplex stainless steel 32205 (standard duplex) and 32304 (lean duplex) were investigated in the as-received state, cold rolling (with thickness reduction of 64 % and 62 % respectively) and after annealing at 1055ºC for 20 s soaking. Crystallographic microtexture was obtained via Electron...

Description
Summary:Samples of duplex stainless steel 32205 (standard duplex) and 32304 (lean duplex) were investigated in the as-received state, cold rolling (with thickness reduction of 64 % and 62 % respectively) and after annealing at 1055ºC for 20 s soaking. Crystallographic microtexture was obtained via Electron BackScatter Diffraction (EBSD) technique. The results showed that the crystallographic microtexture of ferrite phase in the as-received, cold rolled and annealed condition were more intense in alpha fiber= // RD and tetha fiber. The austenite microtexture was shown to be, for all conditions, mainly composed by Brass component.
