Diploma in Metallurgical Engineering Syllabus

The science of making useful products out of metals, focusing on how metal parts are made, their properties, and the cost involved.

A three-dimensional arrangement of atoms in a crystal, which can be defined by its unit cell, the smallest repeating unit.

A regular array of points in space that describes the arrangement of atoms in a crystal.

These are imperfections in the perfect arrangement of atoms in a crystal structure. They can be point defects, line defects, or surface defects.

A line defect in a crystal lattice where atoms are arranged in a non-linear pattern, resulting in a strain field that affects the material's properties.

The process by which atoms move from one position to another within a solid material, driven by a concentration gradient.

The process by which a metal deforms under stress due to the movement of dislocations.

The process by which a metal deforms under stress by forming mirror-like planes within the crystal lattice, resulting in twinned crystals.

A process where a metal's microstructure changes due to heat treatment, resulting in increased ductility and reduced strength.

A process where new, defect-free grains are formed in a metal after being subjected to deformation and annealing.

The growth of larger grains at the expense of smaller ones, leading to both improved strength and reduced ductility.

The size and shape of crystals in a metal, which affects its properties such as strength, ductility, and toughness.

A phase diagram that shows the equilibrium relationships between iron and its carbides at different temperatures and compositions.

A phase diagram that shows the equilibrium relationships between two components in a mixture at different temperatures and compositions.

A type of phase diagram where a solid phase melts into two liquid phases at a specific temperature.

A solid solution where the solute atoms fit into the interstitial spaces between the solvent atoms.

A solid solution where the solute atoms replace some of the solvent atoms in the crystal lattice.

A set of rules that describe the conditions under which a substitutional solid solution can form.

A process where new, stable nuclei form within a liquid or solid phase during solidification, leading to the formation of grains.

The process by which newly formed nuclei grow in size, eventually forming larger grains.

A type of iron that contains a high percentage of carbon, resulting in brittle and rigid material.

A type of cast iron with flake-shaped graphite particles, making it strong and ductile.

A type of cast iron with spherical graphite particles, resulting in high strength and ductility.

A type of cast iron that is malleable and ductile, formed by heat treatment of white cast iron.

A test that measures the resistance of a material to indentation by a hardened steel ball.

A test that measures the depth of penetration of a hardened steel ball or diamond cone into a material.

A test that measures the resistance of a material to indentation by a diamond pyramid.

A test that measures the ability of a material to withstand tensile forces, showing how much force is needed to stretch the material before it breaks.

A test that measures the ability of a material to withstand compressive forces.

A test that measures the ability of a material to deform under stress without breaking.

A test that measures the resistance of a material to repeated stresses, demonstrating how many cycles of stress a material can withstand before it fails.

A test that measures the ability of a material to withstand long-term stress at high temperatures.

A test that measures the resistance of a material to twisting forces.

A test that measures the resistance of a material to shearing forces.

A test that measures the ability of a material to absorb energy before fracturing.
