Obtencion del diagrama esfuerzo-deformacion mediante RVE en un acero AISI 1020 tratado desde temperaturas intercríticas

Abstract

The purpose of this monograph is to analyze an AISI / SAE 1020 steel heat treated from intercritical temperatures, whose percentage of carbon and manganese is low compared to other double-phase steels. A quenching in water was carried out to achieve a transformation in the martensitic matrix. Subsequent to this, tension tests were carried out, as well as the RVE tools, which by means of computational simulations allow to quickly determine predictable results; In our particular case, obtaining the stress-strain diagram graphs very close to the real data taken in the laboratory. After these experiments it was possible to determine the influence of the treatment, in addition to the change of the different mechanical properties in the material.
