OBJECTIVES
Students of Materials Science and Engineering are offered an in depth study of the
physical metallurgy of ferrous and aluminum alloys.
UNIT I PHASE TRANSFORMATION 8
Basics of thermodynamics, kinetics and diffusion mechanisms.
UNIT II DIFFUSION CONTROLLED PHASE TRANSFORMATION 10
Nucleation and growth - Types of nucleation - Concept of free energy during
solidification - Thermodynamics of homogeneous nucleation - critical nucleus size and
critical free energy change - constitutional supercooling - Extension to heterogeneous
nucleation - Nucleation rate and growth rate - overall transformation rate. Concept of
Activation energy - Arrhenius equation - Johnson Mehl - Avrami equation. Pearlitic
transformations.
UNIT III DIFFUSIONLESS TRANSFORMATIONS 10
Martensite transformation - Definition - characteristic features of Martensitic
transformation in steels - morphology of Martensite - lath and acicular martensite -
Crystallography of martensitic transformation - Martensite in non-ferrous systems -
Thermoelastic martensite - Shape Memory effect - Examples and applications of shape
memory alloys.
UNIT IV PRECIPITATION REACTIONS 7
Precipitation from solid solutions, thermodynamic considerations, structure and property
during ageing, sequence of ageing, formation of G-P zones and intermediate
precipitates, theories of precipitation hardening, effect of time, temperature and alloy
compositions, precipitation free zones, crystallographic aspects of transformation,
coarsening kinetics.
UNIT V ANNEALING 8
Cold working and hot working. Recovery - polygonization and dislocation movements in
polygonization. Recrystallisation - effect of time, temperature, strain and other variables,
mechanism of nucleation and growth. Grain growth – Grain growth law, geometrical
collisions, preferred orientation, secondary recrystallisation.
