청구항

1. A method of making a composition, the method comprising: heat treating a material including an iron-based composition at a first temperature under a first condition in which at least some of the iron-based composition is transformed into an austenite phase;cooling the material to a second temperature at a cooling rate under a second condition in which at least some of the iron-based composition is transformed into a martensite phase; andheat treating the material at a third temperature under a third condition in which carbides are precipitated. 2. The...
