RESEARCH ON THE MICROSTRUCTURES AND MECHANICAL PROPERTIES OF Ti MICRO-ALLOYED COLD ROLLED HOT-DIP GALVANIZING DP980 STEEL
Effects of galvanizing simulation parameters on microstructures and mechanical properties of Timicroalloyed cold rolled hot-dip galvanizing DP980 steel were investigated in this study by optical microscopy(OM),transmission electron microscopy(TEM),energy dispersive spectroscopy(EDS)and tensile test.Moreover,the precipitation behavior of Ti in the experimental steel was also studied.The results show that,as the heating temperature increases,the tensile strength of experimental galvanizing DP980 steel decreases while the yield ratio and elongation of the steel are enhanced.The microstructures of experimental steels exhibit typical dual phase steel character and the volume fractions of MA islands are almost 30%.In addition,lots of nano-sized TiC precipitates can be found in the ferrite grains.
