Abstract
The distinction between first-order and second-order phase transformations is brought out. The general characteristics of first-order transformations are described. The salient features of transformations controlled by long-range diffusion, short-range diffusion and by (diffusionless) shear mechanisms are discussed. Martensitic trasnformations, which belong to the shear category, occur in many metallic and non-metallic systems and deserve an intensive study.
