Metals and alloys have been used extensively in personal appliances and industrial instruments due to their excellent mechanical property, as well as electrical and thermal conductivity. Among different types of biomaterials, a favorable combination of high strength and resistance to fracture that metals provide warrants their reliable long-term implant performance in major load-bearing situations. The processing and composition of metals and alloys determine their microstructure and that in turn determine properties. For example, carbon steel which is also known as mild steel is useful for making
