- Abstract
The current trend of hot forming steel is mainly focused on improving the ductility, meanwhile, the new steel was also designed to overcome the surface oxidation and avoid the complexity of cooling system of the stamping dies. This new steel and corresponding forming technology were called low temperature hot forming or warm stamping technology, which overcomes the disadvantages of the conventional hot forming steel. This present work focused on the microstructure characteristics and mechanical behavior of a 0.1C-5Mn-0.02Ti-Fe balance steel warm stamped after different batch annealing temperature. It can be concluded that the microstructure and mechanical characteristics strongly depended on the annealing temperature. These results suggest that when the batch annealing temperature is between 570–630 ℃, the steel exhibits over 1400 MPa tensile strength and 9% total elongation. A distinctly decrease in the tensile strength and total elongation was observed above 690 ℃. These worsen mechanical properties can be attributed to the increased prior austenite grain sizes and fraction of lath martensitic.
