Abstract
A method of forming metal parts or components from strip stock or roll stock without yielding is accomplished by first placing the part/components into fixtures that hold the stock in a non-yielding position therein. The fixture and metal stock parts are placed in a liquid, gas, or pack carburizing heat treatment process. Once the carburization process is complete, the part is released from the fixture with little or no spring back, maintaining the shape it was held in while in the fixture, resisting returning to its original shape, and optionally imparting spring-like qualities not associated with the stock before treatment.
