Question

Cite two major differences between martensitic and pearlitic transformations.

Answer 1

Answer: Two major differences are: 1) atomic diffusion is necessary for the pearlitic transformation, whereas the martensitic transformation is diffusionless; and 2) relative to transformation rate, themartensitic transformation is virtually instantaneous, while the pearlitic transformation is time-dependent.
