Efecto de diferentes porcentajes de deformación sobre un acero con contenido de carbono menor al 0.2% y manganeso mayor al 1.0%

Abstract

In this work, for a steel with content of 0.184% in carbon and 1.141% in manganese, it is intended to determine the influence of plasticity-induced transformation in its properties at the microstructural level before and after being subjected to different percentages of deformation. For this, samples of the compression material were initially deformed with loads between 25 and 40 tons. Subsequently a two-stage heat treatment was carried out, in the first the material was heated for a time of 8 minutes at 750oC, which temperature is 22o above the intercritical temperature Ac1 and corresponds to the transformation point of ferrite-pearlite to ferrite -Astenite. The second stage was to keep the material for 3 minutes at the start temperature of bainitic transformation at 561oC, so that part of the austenite was transformed into martensite. Finally the cooling was carried out at room temperature.
