Validación de las propiedades mecánicas por ensayo de tensión del acero 17-4 PH.

Abstract

In the following article, a validation of the experimental part and simulation of the mechanical properties such as the modulus of elasticity, elastic limit and ultimate stress of 17-4 stainless steel hardened by precipitation was carried out; This investigation was carried out in order to verify if the simulations can be applied to the additive manufacturing of metals, in order to reduce time and costs of the powder bed fusion technique. First, six test tubes were manufactured, varying the thickness and manufacturing angle, to later carry out tensile tests, obtaining the modulus and limit of elasticity; then, after carrying out the experimental tests, the simulations were made as realistic as possible, in order to compare the stress-strain graph obtained by both processes. It was obtained as a result that only one trial had the slope of the similar module in the validation, but the others did not; therefore, other investigations should be carried out to verify if the model used is compliant for additive manufacturing simulations.
