Diffusionless Martensitic Transformation (10P) a. Write at least six important features associated

Diffusionless Martensitic Transformation (10P) a. Write at least six important features associated with martensitic transformation. (3p) b. What are the differences between lath and plate martensite with respect to morphology and formation temperature? (2p) c. Martensitic transformation is diffusionless, i.e., the change in crystal structure is achieved by a homogeneous deformation of austenite. The strain needed was first proposed by Bain in 1924 and is known as the "Bain strain". What is Bain strain? (2p) d. What is autotempering? What are the two factors that the first laths form are thicker than those forming at lower temperatures in autotempering? (3p)
