Description

This program takes the lattice parameters of ferrite and austenite as the inputs. It also takes the correspondence matrix, lattice invariant plane and lattice invariant directions as inputs.

  1. It follows the phenomenological theory of martensite crystallography and calculates the crystallographic set for any transformation. This set consists of the habit plane, shape deformation and orientation relationship

Inputs when running the program

PUT THE AUSTENITE LATTICE PARAMETER:
3.619092
PUT THE FERRITE LATTICE PARAMETER:
2.882

Name

bain_strain.for

This is a source code of this program. For the execution, it needs to be compiled.
compile example :
g77 bain_strain.for -o name.out
