Modeling of grain growth behavior of S34MnV steel at elevated temperatures
S34MnV steel is widely used as a fundamental material in manufacturing crankshaft in diesel engine.However,due to amount of addition of Manganese element in the steel,coarse grain and mixed grain are commonly observed after long time heating during the forging passes in industrial practice,which may seriously reduce the impact toughness of the material.In current study,based on the observed microstructure of S34MnV steel at different temperatures and heating times,an empirical model has been established which reflects the relationship between the final grain size and the initial grain size,as well as heating temperature and holding time.This model has been validated by a scaled sample,and we further represented a successful industrial application of this model to simulate the grain size distribution and evolution during a large crankthrow heating and forging process,which evidences its practical and promising perspective of our model with an aim of widely promoting the mechanical properties heavy marine components.
