Splined component formed by ultra-high strength steel and method for forming same

Disclosed are a method for forming a splined component utilizing ultra-high strength steel and components formed by the method. The method includes the step of providing a flat blank of ultra-high strength 22MnB5 steel. The next step of the method is cold forming the flat blank into an unfinished shape of a component while the blank is in an unhardened state. Then, heating the unfinished shape ofthe component and generating a spline form thereon. The method proceeds by forming a finished shape of the component using a quenching die resulting in a fine-grained martensitic component material structure and enabling net shape processing to establish final geometric dimensions of the component. 种利用超高强度钢形成带花键的部件的方法和通过该方法形成的部件。该方法包括提供超高强度22MnB5钢的板坯料的步骤。该方法的下步是在坯料处于未硬化状态的同时将板坯料冷成形为部件的粗加工形状。然后，对部件的粗加工形状进行加热并在其上产生花键形状。该方法通过使用淬火模具形成部件的成品形状，从而形成细粒度马氏体成分的材料结构并且能够进行净成形处理以确定部件的最终几何形状的尺寸。
