Crystallographic texture evolution in 1008 steel sheet during multi-axial tensile strain paths

Abstract

This paper considers the crystallographic texture evolution in a 1008 low carbon steel. The texture evolution along uniaxial, plane strain and balanced biaxial strain states were measured. For uniaxial testing, grains tend to rotate such that the {111} 110 slip directions are aligned with the loading axis. For plane strain and balanced biaxial strain states, the majority of grains are distributed with the {111} plane parallel to the sample normal direction. Accompanying visco-plastic self consistent (VPSC) predictions of the texture evolution were made along same strain paths and strain increments. Comparing between the measured texture evolution and computational texture evolution indicate that the VPSC model qualitatively predicts the measured texture evolution, but the rate at which the texture evolution occurs is over predicted.

Elastic behaviour of orientation-correlated grains in multiphase aggregates

“…Other possible reasons for a local matrix effect are bimodal textures where two strong texture components pair two different crystal directions in the same sample direction. Examples are found in sheet metal forming textures of steel (Creuziger et al, 2014) where -fibres [(111) || ND] sometimes occur together with cube-and Goss-type textures [(100) || ND], thus leading to grains with orientations (111) || ND preferentially surrounding grains with orientations (100) || ND (Fig. 5).…”

Chaboche Model for Fatigue by Ratcheting Phenomena of Austenitic Stainless Steel under Biaxial Sinusoidal Loading

“…It was a motivating subject for several researchers [21][22][23]. Other researchers look into biaxial fatigue in [24][25][26][27][28]. The notoriety of austenitic stainless steels is based primarily on their excellent mechanical attributes such as ductility, impact resistance, and toughness [29][30][31][32][33][34][35][36].…”
