Abstract
Stainless steels are in most cases polycrystalline. Texture structure often occurs in this type of materials due to thermo-mechanical processes, which can be desirable or undesirable [1]. Both the FCC austenitic stainless steel and the duplex stainless steel, which consists of 50-50 FCC austenite and BCC ferrite, were heat treated at 1100 C for 10 min and then deformed at 61 % and 35 % strains respectively. The texture structures were measured using X-ray powder diffraction with radiation of Cr kα as recrystallization and deformation texture respectively. The results showed that the texture structure was different after recrystallization for the single FCC austenite sample and the FCC-BCC duplex sample. The texture structures after deformation differed even more. This implies that the deformation mechanism for the FCC austenite is different when the second phase, such as BCC ferrite is present. The texture structures of BCC ferrite in the duplex sample was found to deviate from the recrystallization one to the cold deformation one as it expected [2]. The texture structures were analyzed using orientation distribution function (ODF). The detailed analysis will be presented at the conference.
