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
