The Material Orientation Relationship for the BCC-HCP Transition

TL;DR

This paper presents a dynamical model explaining the formation of martensitic crystals during the bcc-hcp transition, linking morphological features to elastic properties of the initial phase.

Contribution

It introduces a model that connects the macroscopic morphological features of the bcc-hcp transition to elastic moduli of the initial bcc phase, providing a new theoretical framework.

Findings

All morphological characters are expressed through elastic moduluses Cij.

The model explains habit plane, macroshear, and orientational relationship.

The approach offers a unified understanding of the bcc-hcp transition morphology.

Abstract

The dynamical model of forming of martensitic crystals for the bcc-hcp transition is offered. It is shown that all macroscopic morphological characters (the habit plane, the macroshear and the orientational relationship) are expressed through elastic moduluses Cij of an initial bcc phase.
