Classification of Materials. Based on Structure • Crystalline material is a material comprised of one or many crystals. In each crystal, atoms or ions show a long-range periodic arrangement. – Single crystal is a crystalline material that is made of only one crystal (there are no grain boundaries). – Polycrystalline material is a material comprised of many crystals (as opposed to a single-crystal material that has only one crystal). • Grains are the crystals in a polycrystalline material. • Grain boundaries are regions between grains of a polycrystalline material.

Environmental and Other Effects • Effects of following factors must be accounted for in design to ensure that components do not fail unexpectedly: • Temperature • Corrosion • Fatigue • Strain Rate Manufacturing materials --- IE 251 lect-4, lect-4 Slide 8
