ABSTRACT
The principles of grain growth and the various approaches to this phenomenon were described in Chapter 3, whilst the inhibition of grain growth, both in bulk material and in foils was described in Chapter 4. Particular attention was directed to the inhibition effects of second phase particles, whilst Chapter 5 was concerned with the precipitation behaviour of second phase particles, and with subsequent coarsening of the particles on holding at elevated temperature. Although much of the detailed material concerned the grain refinement of steel, reflecting the author’s particular area of study, the principles are applicable to any polycrystalline material. In this, the final chapter, the application of these principles are considered in relation to grain growth following allotropic transformations and grain growth following hot work, or cold work and re-crystallisation. The effects of particles on the recrystallisation process itself is also considered in terms of the inhibition of sub-grain growth.
