INDUSTRIAL MATERIALS

Specific Foundation / Core

The course is also offered to exchange programme students.

This course aims to introduce students to postgraduate level concepts and techniques that provide the necessary background in specialized subjects. Also, the course assimilates the background of graduates from different Departments and Universities.

Isothermal and continuous cooling transformation (TTT-CCT) diagrams. Cast irons. Physical properties and alloying phenomena. Copper alloys. Brass. Bronzes. Light-metal alloys. Aluminum alloys. Titanium alloys. Superalloys. Strengthening mechanisms. Powder metallurgy. Oxide-dispersion-strengthened superalloys. Ceramic materials: Introduction to traditional and advanced ceramics and to mechanical and thermal properties and comparison with other materials. Atomic binding, lattice types, point and line flaws and influence on properties. Catalysts, pigments, sensors and other special ceramics. Diffusion and sintering. Fracture toughness, toughness, strength and fracture. Composite ceramics, toughening and fracture energy dissipation. Methods of processing and production of ceramics. Applications of ceramics. Current research directions in ceramic materials. Polymers & colloids: In addition to the daily applications of polymers (plastics, paints, fabrics), the development of polymeric materials that mimic the respective biological molecules (cellulose, DNA, proteins) has revolutionized fields such as replacement of human members (artificial bones, heart, lungs, arteries) or controlled transport and release of drugs in cancer chemotherapy. Synthetic polymers are used to enhance the thermal / mechanical properties of aircraft or even microelectronic computer and printer systems. On the other hand, colloidal dispersion systems are the primary method for the synthesis and management of nanoparticles. Otherwise, most of the properties and applications of nanoparticles are based on the solid phase stability in a solvent. For example, the degree of incorporation of nanomaterials in biological systems depends on their dispersal quality and the existence of functional groups around them. Likewise, obtaining monolayer coatings can be accomplished with the appropriate colloidal nanoparticulate solutions.
