Quantitative Analysis of Micro‐Textures during Recrystallization in an Interstitial‐Free Steel

Abstract

Two interstitial-free steel samples were prepared by normal and by cross rolling. The effect of the resulting different deformation textures and microstructures on the subsequent recrystallization behavior was studied by micro-texture analysis. The differences in recrystallization textures of the two differently rolled samples can be attributed to the microstructural differences in the as-deformed state. The orientation distribution of the recrystallized grains forming at the early stages of the recrystallization dominated the final recrystallization textures, pointing to the importance of oriented nucleation in the formation of recrystallization textures of interstitial-free steels.

Effect of hot band grain size on development of textures and magnetic properties in 2.0% Si non-oriented electrical steel sheet

“…These findings are in accord with the processes of nucleation and growth in conventional lowcarbon steel grades [27]. After annealing at 800 and 900 C, the microstructures of the SG sample display a continuous increase in grain size with increasing annealing temperature ( Fig.…”

“…The core loss W 15/50 () displayed the opposite behavior ( Fig. 10 conventional low carbon steel sheets [24,27]. However, the cold rolling textures of the SG and LG samples differ from those commonly observed in NO electrical steel sheets which usually comprise a strong <110>//RD fiber with a maximum at the orientation {112}<110> [10,18].…”

“…The magnetic properties at final gauge were measured by a single-sheet tester [10,12,17] resemble those of low carbon steel sheets in which the orientations are likewise assembled along the <110>//RD and <111>//ND fibers [24,27]. As such, the rolling textures of the present samples differ from those commonly observed in NO electrical steel sheets, which display strong <110>//RD fiber textures with a maximum at {112}<110> as reported elsewhere [10,18].…”

Comparative Study of Microstructure, Texture, and Formability Between 11CrTi and 11CrTi+Nb ASTM 409 Ferritic Stainless Steel

“…The recrystallization was evaluated by Grain Orientation Spread (GOS). This is determined by the mean orientation of the grain and each pixel in the grain, the result is a mean deviation in orientation 10,11 . In this present work, cut off values of GOS≤1° were chosen for recrystallized grains.…”
