ETM 3900 - Industrial Materials

• Be able to rationally identify which plastic materials are best aligned with which processes (Injection, compression molding, extrusion, etc.).
• Be familiar with the relative hierarchy of metals with respect strength, hardness, ductility, toughness, etc.).
• Be familiar with the typical metals used in industry by name, and characteristic (Carbon steel, alloy steel, stainless steel, tool steel, ferrous powdered metalurgy (P/M) aluminum, cast iron, etc.).
• Have a general familiarity with the typical alloying elements used with aluminum and iron, and the effects they produce in engineering characteristics.
• Understand techniques for altering grain size.
• Understand the effects of grain size and grain orientation upon engineering material characteristics.
• Understand the primary engineering material characteristics (modulus of elasticity, yield strength, ultimate strength, ductility, hardness, toughness, brittleness, fatique strength, critical temperature, melting point).
• Understand the properties and engineering characteristics (strength, hardness, temperature limits) of the typical plastic materials used in industry (polyethelene, polystyrene, polycarbonate, epoxy, etc.).
• Understand types of and differences in crystal lattice structure (bcc, fcc, hex, etc.).
