metalsmost elements exist as metal alloysa homogenous mixture of two or more elements at least one of which is a metal, and where the resulting material has metallic properties intermetallic compoundsimilar to alloy but the mixture exists as a stoichiometric compound (distinct atomic ratios) ceramicsinorganic, non-metallic substances ceramicssolids formed between metallic and nonmetallic elements, most frequently oxides nitrides and carbons

response of materials to heat increase heat capacity; changes in phase lead to absorption of heat, thermal conductivity; failure - thermal shock phonon a quantum of energy resulting from vibrational waves in a solid heat capacity represents the energy required per unit mass to change the temperature of a substance by 1 degree C thermal expansion an increase in temp leads to a greater amplitude of atomic vibrations within a solid; coefficient of thermal expansion alpha thermal condu...
