Dilatometric Analysis of Continuous Cooling Bainite Transformation in Low Carbon Microalloyed Steel

Liangyun Lan

Abstract


The effect of reheat temperature on the continuous cooling bainite transformation in a low carbon microalloyed steel was investigated using a dilatometer based on welding thermal simulation process. At a given cooling rate, the fine grained heat affected zone with reheat temperature of 1050 ℃ has the lowest bainite start and finish temperatures and highest transformation reaction rate among the sub-zones of heat affected zone.
