1. Introduction and point groups Stereographic projections Low symmetry systems Space groups Deformation and texture Interfaces, orientation relationships Martensitic transformations Interfaces Crystallography H. K. D. H. Bhadeshia Dislocation structure of arbitrary interfaces

3. Burgers circuit across an interface (A S A) deforms lattice A into B (A S A) -1 deforms lattice B into A

4. p = OP closure failure PP’=b t where b t is total Burgers vector crossing a vector p in interface

5. Arbitrary misfit at the interface can be accommodated by three sets of dislocations with Burgers vectors b 1, b 2 and b 3

12. Coincidence site lattice

13.  =7

15. u x xx

16. primitive lattice vector of A primitive lattice vector of B, not of A must be a CSL vector with integral components in A and B integral elements
