Experimental Analysis of Hardness Distribution of the Transition Region in Tailored Tempering Stamping of Ultra-High Strength Steel

Abstract:

With hot forming parts of ultra-high strength steel (UHSS) widely used, requirements on matching the mechanical properties of parts with the performance on active service are attracting attention. Research shows that the preheat temperature of the molds set to 400°C or above can effectively reduce the hardness of the sheet and get a better region. The width of the air gap between tools is important influencing factor. Too large air gap will increase the difficulty of controlling the region of variable intensity and the position of ultimate strength.
