Sphere packings as a tool for the description of martensitic phase transformations

Sphere packings as a tool for the description of martensitic phase transformations Martensitic transformations which play an important role in metallurgical processes are analysed using group–subgroup relations and sphere‐packing considerations. This approach is applied to the transformations between body‐centred cubic (b.c.c.) and face‐centred cubic (f.c.c.) phases and yields the orientation relations according to the Nishiyama–Wassermann, the Kurdjumov–Sachs and the Pitsch mechanisms. The models proposed by Pitsch and Schrader and by Burgers for the transition between b.c.c. and hexagonally closest‐packed (h.c.p.) type structures can be interpreted analogously. In addition, two mechanisms for the transition between cubic f.c.c. and h.c.p. structures are described. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Acta Crystallographica Section A Foundations of Crystallography Wiley

Abstract

Martensitic transformations which play an important role in metallurgical processes are analysed using group–subgroup relations and sphere‐packing considerations. This approach is applied to the transformations between body‐centred cubic (b.c.c.) and face‐centred cubic (f.c.c.) phases and yields the orientation relations according to the Nishiyama–Wassermann, the Kurdjumov–Sachs and the Pitsch mechanisms. The models proposed by Pitsch and Schrader and by Burgers for the transition between b.c.c. and hexagonally closest‐packed (h.c.p.) type structures can be interpreted analogously. In addition, two mechanisms for the transition between cubic f.c.c. and h.c.p. structures are described.
