ME 511 Engineering Materials and Characterization (3-0-0-6)
Introduction and classification of materials: metals and alloys, ceramics, polymers and composite. Atomic bonding, crystal structure and grain morphology. Defects in metals. Plastic deformation mechanisms of metals: dislocation slip, deformation twinning, martensitic transformation. Strengthening mechanism of metals. Failure mechanisms: fracture, fatigue and creep. Phase diagrams (Fe-Fe3C phase diagrams), TTT and CCT diagram. Heat treatment. Powder metallurgy. Coating techniques. Composite fabrication: metal matrix, polymer matrix and ceramic matrix composites. Introduction to advanced materials: shape memory alloys, piezoelectric materials, biomaterials, superalloys, high entropy alloys.
Mechanical characterization: tensile test, hardness test, impact test, fracture/fatigue/creep test; X-ray diffraction (XRD) technique: characterization and analysis; Microscopy techniques and analysis of results: optical microscopy (OM), scanning electron microscopy (SEM), energy-dispersive X-ray spectroscopy (EDS/EDX/EDAX), electron backscatter diffraction (EBSD), transmission electron microscopy (TEM), atomic force microscopy (AFM), scanning tunneling microscopy (STM); Principles and applications of thermal analysis: differential thermal analysis (DTA), differential scanning calorimetry (DSC), thermogravimetric analysis (TGA), thermomechanical analysis (TMA), dynamic mechanical analysis (DMA/DMTA).
