Introduction: Types, driving force and kinetics of phase transformation in metals and alloys

Diffusional phase transformations:

• Nucleation reactions, different types of interfaces, growth mechanisms, transformation kinetics
• alpha to gamma transformation; Eutectoid transformations; Precipitation in age hardening alloys; Spinodal transformation; Massive transformnation, Ordering transformation

Diffusionless phase transformations:

• Characteristics and crystallography
• Nuclation and growth mechanisms
• Shape memory effect
