7 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.

8 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
