In this study, the effects of thermomechanical heat treatments on two batches of commercial
AISI 1070 steel were investigated. Both samples underwent cold rolling and
annealing at 600 oC for 30 min, and their microstructure and crystallographic texture were
analyzed using XRD, SEM observations, and EBSD measurements. Tensile testing was also
conducted to evaluate the mechanical properties of the steels. The results showed that the
lamella pearlitic microstructure of both samples was transformed into a-ferrite matrix
with spheroidal cementite particles (Fe3C). Sample A exhibited a strong g-fiber texture
parallel to the rolling plane, with a typical cold-rolled texture and high anisotropic characterization
dominated by (111) orientation. Sample B, on the other hand, exhibited
(111)[121] and GOSS (110)<001> texture components with dominant (111) and (101) grain
orientations along the rolling direction. While the yield stress and tensile strength were
higher in sample A, sample B had better toughness and elongation properties, indicating
that it was more ductile. These findings highlight the importance of controlling heat
treatment processes to achieve desired microstructures and mechanical properties in
steels and provide insights into the relationship between microstructure, crystallographic
texture, and mechanical properties. The results of this research could be useful in optimizing
the process and performance of steels in various industrial applications.
