Investigating the Effect of Cast Structures on Texture and Mechanical Properties of AISI 433 Ferritic Stainless Steel | Chapter 9 | Advanced Aspects of Engineering Research Vol. 12

 Using the electron backscatter diffraction (EBSD) technology, the effects of the individual equiaxed and columnar cast structure on the evolution of texture during thermo-mechanical processes (TMP) was examined. The impact of individual IECS versus ICCS on texture evolution during the rolling and annealing processes was examined in this work. The mechanical properties of the initial cast structures were then linked to the recrystallization texture after cold working and annealing. It was discovered that The columnar produced an inhomogeneous texture with a majority of both the Goss and fibre textures, whereas the initial equiaxed cast structure had a homogeneous fibre texture. While texture has a significant impact on the drawn product's surface smoothness, it was discovered that it had a minor impact on yield strength and ultimate tensile strength (UTS), with the elongation of the equiaxed cast structure being slightly higher than the columnar cast structure measured parallel to the rolling direction (RD).
