OUTCOMES 

• The course seeks to develop and understanding of the thermodynamic during force for the phase transformation and the role that chemical during forces strain energy and interfacial energy play in powdering or modifying these during forces .
• Ability to calculate single component and multi component phase diagram from thermodynamic data or solution models.
• An appreciation of the importance and energy characteristic of surface and interfaces and their impact on equilibrium microstructures and capacity drives process.
• Ability of solve problems involving steady state and non steady state diffusion of varying degrees of complexity and to understanding the spatio temporal sealing behavior of solution to such diffusion problems.
