Alloy it or work harden it.

The leaned techniques to harden iron weapons.
Cut a straight piece of metal coat hanger, about 10 inches long. Bend it back and forth a few times. The point where the bend is will now be work hardened. *If you repeat this bending too many times, it will break because the hardening also makes it brittle.

Metal alloys are primarily created by being heating, melting and blending, then allowed to cool and harden. This is common in alloy manufacturing plants.
Manufacturers heat treat metal for a variety of reason. One reason is to alter the physical appearance of the metal. Another reason is to harden the metal. They may even heat treat the metal in order to soften the metal to make it more malleable.
Get a metal rod, heat it really hot wrap it around a metal pipe a little bigger than your wrists. and dunk it in water to harden.
