The invention discloses a method for forming varied strength zones of a vehicle component. A vehicle component strength zone forming method is provided. The method includes identifying a condition ofa blank via sensors at a furnace inlet. The method further includes outputting, by a controller, furnace command signals based on a predetermined thermal treatment schedule for the identified condition of the blank to heat a first blank portion to form a fully martensitic microstructure and heat a second blank portion to form a microstructure having one or more of ferrite, pearlite, and austenite.The method may further include outputting the furnace command signals based on furnace temperature variations detected by furnace sensors in communication with the controller. The method may furtherinclude outputting the furnace command signals based on one or more of a detected blank chemical composition, a detected type of blank coating, a detected blank thickness, and a detected blank material type. 公开了用于形成车辆部件的不同强度区域的
