Interface Migration

Question 1

Heterogeneous

Answer 1

(can be divided into parent and product phases)
> nucleation
> includes thermal and athermal

Question 2

Glissile

Answer 2

> athermal, shearing of parent lattice into product
parent and product have similar structure
coherent interface
military transformations
must be diffusionlesss (no change in composition)

Question 3

Non-glissile

Answer 3

> thermal activation, random jumps of individual atoms
parent and product have different structure
coherent or incoherent interface
civilian transformations
can be diffusional or diffusionless

Question 4

Interface controlled

Answer 4

no change in composition (parent and product have same)

Question 5

Diffusion controlled

Answer 5

change in composition

Question 6

Mixed control

Answer 6

interface and diffusion controlled
