EFFECT OF C-Mn PARTITIONING ON THE MICROSTRUCTURE AND MECHANICAL PROPERTIES OF TRIP STEEL

In this paper, the TRIP590 steel was used for C-Mn partitioning. The influence of partitioning on microstructure and mechanical properties studied. SEM, EPMA, XRD tensile tests were to characterize tested steel, calculate content retained austenite, analyze enrichment C atoms Mn properties. results show that there a lot lath martensite scattered ferrite in microstructures Q&P steel. After partitioning, increased. relatively apparent, concentration center significantly higher than at boundary between ferrite. Mn-rich areas also C-rich areas. Compared with had larger amount elongation PSE.
