: Reheating quenched steel to trade some hardness for toughness, preventing the part from shattering during use. 4. Mechanical Testing and Properties
: Exceptional strength and heat resistance for turbine engines and medical implants. 6. Corrosion and Degradation
: Occurs when two different metals are in electrical contact in a corrosive environment.
Metallurgists must protect metals from chemical attack by their environment. : The reaction of metal with oxygen.
: Heating and slow cooling to soften the metal and improve ductility.
: Brass (Cu-Zn) and Bronze (Cu-Sn) for corrosion resistance and conductivity.
