Module Contents

Principles of allying. Solid solution, intermetallic phases, ordered structures. The kinetics of Nucleation and Growth. The mechanism of Diffusion. Surface energy. The controlled between phases. The homogenous and heterogeneous nucleation at liquids and solids. The recovery and recrystalization. The grain boundary segregation. The age hardening. The diffusionless transformations. Martensitic transformations. Shape memory alloys. Classification of materials. Metallic materials. Metal deformations. Plastic deformation of materials. Metal alloys. Iron based materials. Ceramic materials. Metallic conductors. Semiconductor materials. Magnetic materials


Aims and Objectives of the module

The aims of this course are focused on learning the principles of the alloying and during alloying the states when we observe the solid solutions, intermetallic phases and ordered structures. Moreover, the mechanisms of the nucleation and growth are given. The diffusion mechanism is important during diffusional transformation hence; first of al this mechanism explained and then difusional process are explained. Other difusional process such as recovery, recrystalization, grain boundary segregation, age hardening are aimed to learn. As diffusionless processes the information about martensitic transformation, shape memory alloys are given.


Method of assessment

One written midterm exam (40%) and one written final exam (60%)
