Microstructural evolution and texture analysis after 80% cold rolling and subsequent annealing in the temperature range of 750-1050 C is surveyed in Alloy-28. This is precisely studied through electron back scattered diffraction and also is declared through elaborating the hardness map. The occurrence of partially recrystallization is clearly evident in the microstructure which was treated 850 C annealing for 30 min. The recrystallization process is completed at 950 C even after 3 min, but in an inhomogeneous manner, that is, coexistence of relatively large and fine recrystallized grains. This microstructure contains a high volume of special grain boundaries ended to the complete and homogenous recrystallization at 1050 C, where further grain growth is occurred with increasing time. Texture analysis shows the retaining of Goss texture after annealing at 850 C and this component is introduced as the main reason for retarding recrystallization and, therefore, creation of inhomogeneous microstructure. Finally, the specimens processed at 1050 C indicate the α-fiber texture due to occurrence of grain growth. The mechanical properties improvement is mainly attributed to the development of S component and also formation of high fraction of annealing twin. Although, predominant the appearance of Goss texture and grain growth are also known as the main reason for deteriorating strength.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
