Unit IV
PRECIPITATION REACTIONS 9
Precipitation reaction – 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
RECOVERY, RECRYSTALLISATION AND GRAIN GROWTH 9
Cold working and hot working, recovery – polygonisation and dislocation movements in polygonisation, 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.
Course Outcomes:
Upon Completion of the course the students will be able to:
- Explain the various diffusion mechanisms and the thermodynamic and kinetic principles.
- Classify the various diffusion controlled transformations and infer the effect of various parameters on the kinetics and growth of nucleation
- Compare the differences between the diffusion controlled and diffusionless transformations and explain the diffusionless transformations in steels and non-ferrous alloys.
- Interpret the thermal cycle on the alloys and the effect of time, temperature and composition during precipitation hardening.
- Recall the concept of recovery, recrystallization and grain growth in cold worked and hot worked steels.
