Factors Affecting Material Selection
hardening, strain rate effect, vibration resistance, wear.• Thermal: e.g. thermal conductivity, expansion coefficient, Resistivity, thermal shock resistance, thermal diffusivity.• Electrical: e.g. conductivity, resistivity, dielectric strength, thermoelectricity, superconductivity, electric hysteresis.
• Magnetic: e.g. ferromagnetism, paramagnetism, diamagnetism, magnetic permeability, coercive force, curie temperature, magnetic hysteresis.
• Chemical: e.g. reactivity, corrosion resistance, polymerization, composition, acidity, alkalinity.
• Optical: e.g. reflectivity, refractivity, absorptivity, transparency, opaqueness, color, luster.
• Metallurgical: e.g. grain size, heat treatment done / required, anisotropy, hardenability.
2. Constraints
• Design Requirements
• Existing Facilities
• Availability
• Compatibility
• Marketability
• Manufacturability (Fabricability / Castability / Formability / Machinability / Weldability)
• Cost (Material + Fabrication / Manufacturing)
