Material Science

Material science is the study of the structure-properties relationship of engineering materials such as metals, polymers, ceramics, composites, and some advanced materials. It aims to understand how the composition and arrangement of atoms and molecules affect the physical, chemical, mechanical, electrical, optical, thermal, magnetic, and biological properties of materials. It also seeks to develop new materials or improve existing ones for various applications.

Classification of Materials

Materials can be classified into four main categories: metals, polymers, ceramics, and composites. Each category has its own characteristics, advantages, and disadvantages.


MetalsMaterials that are composed of one or more metallic elements. They have high electrical and thermal conductivity, high strength and ductility, high melting point, lustrous appearance, and metallic bonding.Iron, copper, aluminum, steel, brass, bronze.

PolymersMaterials that are composed of long chains or networks of repeating units called monomers. They have low density, low strength and stiffness, low melting point, high flexibility and elasticity, poor electrical conductivity, covalent bonding.Polyethylene, polypropylene, nylon, rubber.

CeramicsMaterials that are composed of one or more non-metallic elements or compounds. They have high hardness and brittleness, high melting point, low electrical conductivity (except some semiconductors), high thermal resistance (except some superconductors), ionic or covalent bonding.Silicon dioxide (glass), aluminum oxide (alumina), silicon carbide (carborundum), zirconium oxide (zirconia).

CompositesMaterials that are composed of two or more different materials with different properties. They have enhanced properties that are superior to those of their constituents. They can be classified into matrix composites (where one material surrounds another) or particulate composites (where one material is dispersed in another).Fiberglass (glass fibers in polymer matrix), concrete (cement with sand and gravel), carbon fiber reinforced polymer (carbon fibers in polymer matrix)

Structure and Properties of Materials

The structure and properties of materials can be studied at different levels: atomic, molecular, microscopic, and macroscopic. Each level reveals different aspects of the material's behavior and performance.

  • Atomic level: This level deals with the arrangement and bonding of atoms in a material. It determines the type and number of phases (solid, liquid, gas) present in a material, as well as the crystal structure (lattice type and symmetry) of a solid phase. The atomic level also affects the chemical reactivity, solubility, and diffusion of atoms in a material.

  • Molecular level: This level deals with the shape and size of molecules in a material. It determines the degree of polymerization (number of monomers in a chain) and cross-linking (number of bonds between chains) in polymers, as well as the orientation and packing of molecules in a material. The molecular level also affects the thermal expansion, viscosity, and elasticity of a material.

  • Microscopic level: This level deals with the arrangement and interaction of grains, fibers, particles, or other structural units in a material. It determines the grain size, shape, orientation, and boundaries in metals and ceramics, as well as the fiber length, diameter, orientation, and distribution in composites. The microscopic level also affects the strength, toughness, ductility, and fracture of a material.

  • Macroscopic level: This level deals with the overall shape and dimensions of a material. It determines the geometry, surface area, volume, density, and porosity of a material. The macroscopic level also affects the stress, strain, deformation, and failure of a material.

Processing and Fabrication of Materials

The processing and fabrication of materials involve various techniques to modify or shape materials for specific applications. Some common techniques are:

  • Casting: This technique involves pouring molten metal into a mold and letting it solidify into a desired shape. Casting can produce complex shapes with good surface finish and dimensional accuracy. However, casting can also introduce defects such as porosity, shrinkage, cracks, and segregation.

  • Forging: This technique involves applying compressive force to deform metal into a desired shape. Forging can improve the strength and toughness of metal by aligning the grains along the direction of deformation. However, forging can also cause residual stress, distortion, and surface damage.

  • Rolling: This technique involves passing metal between two rotating rolls to reduce its thickness and increase its length. Rolling can produce large quantities of metal sheets or strips with uniform thickness and good surface quality. However, rolling can also cause work hardening (increase in hardness due to deformation), anisotropy (variation in properties due to direction), and edge cracking.

  • Extrusion: This technique involves forcing metal through a die to produce a long product with a constant cross-section. Extrusion can produce complex shapes such as tubes, rods, wires, profiles, etc. with good surface finish and dimensional accuracy. However, extrusion can also cause high friction, high temperature, high pressure, and die wear.

  • Drawing: This technique involves pulling metal through a die to reduce its diameter and increase its length. Drawing can produce fine wires or fibers with high strength and ductility. However, drawing can also cause necking (reduction in cross-section due to tensile stress), breakage, and surface defects.


Metallurgy is the study of the extraction, production, properties, and applications of metals and alloys. It aims to obtain pure metals from their natural sources, modify their composition and structure to enhance their performance, and use them for various purposes.

Classification of Metals

Metals can be classified into two main categories: ferrous and non-ferrous metals. Each category has its own characteristics, advantages, and disadvantages.


Ferrous metalsMetals that contain iron as the main element. They have high strength, hardness, and magnetic properties, but low corrosion resistance. They are widely used in construction, transportation, and machinery.Iron, steel, cast iron, wrought iron.

Non-ferrous metalsMetals that do not contain iron as the main element. They have low strength, hardness, and magnetic properties, but high corrosion resistance. They are widely used in electrical, electronic, and decorative applications.Copper, aluminum, zinc, tin, lead, gold, silver.

Extraction and Refining of Metals

The extraction and refining of metals involve various processes to separate metals from their ores (minerals that contain metals) and purify them from impurities. Some common processes are:

  • Pyrometallurgy: This process involves heating the ore in the presence of a reducing agent (such as carbon or hydrogen) or an oxidizing agent (such as oxygen or sulfur) to extract the metal. Pyrometallurgy can produce metals such as iron, copper, zinc, lead, etc.

  • Hydrometallurgy: This process involves dissolving the ore in a suitable solvent (such as water or acid) and precipitating the metal by adding a reagent (such as hydroxide or sulfide). Hydrometallurgy can produce metals such as aluminum, nickel, cobalt, etc.

  • Electrometallurgy: This process involves passing an electric current through an electrolytic cell that contains the ore or metal in a liquid or molten state. Electrometallurgy can produce metals such as aluminum, magnesium, sodium, etc.

  • Refining: This process involves removing impurities from the extracted metal by physical or chemical methods. Refining can improve the purity, quality, and properties of the metal. Some common methods of refining are distillation (separating by boiling point), zone refining (separating by melting point), electrolysis (separating by electric potential), and leaching (separating by solubility).

Production and Properties of Alloys

An alloy is a mixture of two or more metals or a metal and a non-metal. The production of alloys involves melting the components and mixing them in a desired proportion. The properties of alloys depend on the composition, structure, and processing of the alloy. Some common properties of alloys are:
