INFLUENCE OF THE CYCLES OF HEAT TREATMENTS ON THE STRUCTURE AND MECHANICAL PROPERTIES OF A DUAL-PHASE STEEL WITH LOW MANGANESE CONTENT
Abstract
This article presents the results of the studies that were conducted by the authors for determining the influence of the cycles of heat treatments on the structure and mechanical properties of dual-phase steel with a low manganese content. For the research in discussion, was used an alloy with 0.094% C and 0.53% Mn which was subjected to several cycles of heat treatments (consisting of full annealing, normalizing, subcritical annealing, full quenching, intercritical quenching). The metallographic analyzes were performed with a LEXT OLS4100 Laser Microscope and OLYMPUS Stream MOTION Image Analysis Software. Furthermore, the mechanical tests were carried out with a QUASAR 600 universal testing machine. The full annealing, normalizing, and the cycle made up of normalizing plus subcritical annealing, all led to the obtaining of ferrite-pearlite structures with different structural aspects and with different percentages of ferrite and pearlite. On the other hand, the full quenching caused the formation of martensite and a small volume fraction of residual austenite. The intercritical quenching, which ended the cycles of the heat treatments, ensured the obtaining of ferrite-martensite structures specific to dual-phase steels; volume fraction, shape, size and distribution of the martensite were influenced by the heat treatments prior to the intercritical quenching. In general, the increase in the volume fraction of martensite within the structure has led to an increase in mechanical strength and a decrease in the deformability of dual-phase steel. This evolution of the mechanical properties was highlighted only in the specimens that were subjected to the cycles of heat treatments ?full annealing + intercritical quenching?, ?normalizing + intercritical quenching? and ?full quenching + intercritical quenching?. However, a deviation from this rule was found in the case of specimens to which the cycle of heat treatments ?normalizing + subcritical annealing + intercritical quenching? was applied.
