Influencia del tiempo de tratamiento isotérmico en la microestructura de un acero con contenido de silicio cercano al 1.5% y deformado plásticamente al 50%

Abstract

Currently, the TRIP steels (Transformation induced by plasticity) have become a determinant material at an industrial level, in the automotive industry, the results of the use of these materials in the components of automobiles have been studied. recent years Up to a figure above 70%. A good combination of properties: good mechanical strength and good ductility. In this investigation a plastically deformed steel was obtained with a 50% reduction and treated isothermally in two time lapses. For this purpose, a percentage of 1.5% of silicon can be used as an external element, in order to achieve an adequate state of the cement, thus obtaining an austenite enriched in the final microstructure. What is the amount of time for the treatment to be most optimal among the employees (4 or 8 hours)?
