Classification of MaterialsBased 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
