 -- COURSE OBJECTIVES
 -- COURSE LEARNING OUTCOMES
The aim is to attain further conceptual knowledge in the field of atomic
diffusion and practice the ability of mathematically analyzing and solving
problems. Further, by realizing aspects of the underlying facts and driving forces
and energies in related mechanisms encountered and so the physical changes in the micro-structure of the metallic materials.
Throughout the course students are expected to achieve the awareness of the facts and so the talent of designing new materials if necessary.
materials if necessary.
