The specimens were fabricated from Dual-Phase (DP) and a Transformation Induced Plasticity (TRIP) sheets with 0.78 mm and 1.08 mm thick, respectively. Experiments to determine the elastoplastic properties, anisotropy, and Young&#8217;s modulus variation were conducted. From the experimental results, it can be observed that the annealing process has a significative effect on the yield stress of the material and on the plateau appearance in the elastoplastic transition zone. Also, the anisotropy of the sheet is significatively reduced when temperatures of 400 °C y 800 °C are used in the process.]]></p></abstract>
<abstract abstract-type="short" xml:lang="es"><p><![CDATA[Resumen Este artículo presenta los resultados experimentales de la influencia de un proceso de recocido en las propiedades anisotrópicas y elastoplásticas de dos tipos de aceros avanzados de alta resistencia. Los especímenes fueron fabricados de un acero tipo Dual Phase (DP) y de un acero tipo Transformation Induced Plasticity (TRIP) con espesor de 0.8 mm y 1.1 mm, respectivamente. Se realizaron experimentos para determinar las propiedades elastoplásticas, anisotropía y variación del módulo de Young a temperatura ambiente y con dos temperaturas de recocido. De los resultados experimentales, se puede observar que el proceso de recocido tiene un efecto significativo en el esfuerzo de cedencia del material y en la generación del plateau entre la zona de transición elastoplástica. Por otro lado, la anisotropía de la lámina es reducida de forma significativa con las temperaturas de 400 °C y 800 °C utilizadas para el proceso de recocido.]]></p></abstract>
