Effect of Grain Size and Annealing Condition on Grain Boundary Segregation of Carbon Atoms in ULC Steel

Abstract:

The grain boundary segregation of carbon atoms is influenced by grain size and annealing condition. Increasing grain size and improving the final cooling ( ＜400 oC) rate can improve the bake hardening property, due to the decreasing of carbon segregation at grain boundaries. Cooling rates have a great effect on bake hardening property of ULC steel with smaller grains
