Evaluation of the orientation relations from misorientation between inherited variants: Application to ausformed martensite

This paper describes a way to deduce the orientation relation occurring in phase transformation by only considering three misorientations between variants inherited from the same parent grain at a triple point. The method, named XABX, can be successfully applied even in materials deformed before phase transformation. This new approach, developed for investigating orientation relations in steels, is easily transposable for studying orientation relations of other phase transformations.
