Classification of Engineering Materials Classification of engineering materials: metals, ceramics, polymers, composites and advanced materials, with properties, bonding, uses and a selection example. Fatigue Failure: Causes, S-N Curve and Prevention Fatigue failure explained: cyclic stress, crack initiation and growth, the S-N curve, endurance limit, Goodman line, stress concentrations and an example. Heat Treatment of Steel: Annealing to Tempering Heat treatment of steel explained: annealing, normalizing, hardening, quenching, tempering, case hardening, TTT diagrams, hardenability and an example. Iron-Carbon Phase Diagram Explained Iron-carbon phase diagram explained: phases, ferrite, austenite, cementite, pearlite, eutectoid and eutectic points, critical lines and a lever rule example. NDT Methods Compared: UT, RT, MT, PT and ET NDT methods compared: visual, penetrant, magnetic particle, eddy current, ultrasonic and radiographic testing, how each works, what it finds and a UT example. Tensile Test: Procedure and Stress-Strain Curve Tensile test explained: specimen, procedure, stress-strain curve, yield strength, UTS, elongation, reduction of area, Young's modulus and an example. Thermoplastics vs Thermosets: Differences and Uses Thermoplastics vs thermosets compared: molecular structure, behaviour on heating, processing, properties, recycling, common examples and an example. Types of Corrosion and How to Prevent Them Types of corrosion explained: uniform, galvanic, pitting, crevice, intergranular, SCC, erosion and MIC, with prevention methods and a worked life example. Types of Welding Processes: SMAW, GMAW, GTAW and SAW Types of welding processes compared: SMAW, GMAW (MIG/MAG), FCAW, GTAW (TIG) and SAW, how they work, shielding, uses, pros and cons and a heat input example.
