|Objectives :– understand the stress –phase transformation interactions and know the basis of their modelling
– unsderstand how these interactions intervene in heat treatment processes, welding….
|Pre-requirements : basis in solid-solid phase transformations and mechanical behaviour of materials|
|Educational content of the course
Analysis of the stress-phase transformation interactions: effect of stresses on equilibrium, on nucleation, on growth and on the microstructures. Examples: coherent precipitation, diffusion dependent transformations, martensitic transformation of metallic alloys.
– Consequences on the mechanical behaviour during phase transformation : transformation plasticity mechanisms – modelling of transformation plasticity
– Taking account of the stress-phase transformation interactions in the prediction of internal stresses and deformations during heat treatment. Analysis of their role.
