Examples of these materials, like martensite or cementite, are (*) combinations of ferrite and austenite.
These substances must obey the Hume-Rothery rules. These materials are strengthened during precipitation hardening, which prevents the movement of dislocations. They have both a solid·us and a liquid·us melting point, and also may have a eutectic point. These substances form when atoms substitute or interstice into a crystal lattice. Examples of these materials, like martensite or cementite, are (*) combinations of ferrite and austenite. When they contain mercury, they are called amalgams. They are equivalent to solid solutions. For 10 points, name these materials like pewter, steel, and bronze, which are mixtures of metals.
These substances must obey the Hume-Rothery rules. These materials are strengthened during precipitation hardening, which prevents the movement of dislocations.
