Parent grain reconstruction from partially or fully transformed microstructures in MTEX

Journal Article


Abstract


  • A versatile generic framework for parent grain reconstruction from fully or partially transformed child microstructures has been integrated into the open-source crystallographic toolbox MTEX. The framework extends traditional parent grain reconstruction, phase transformation and variant analysis to all parent-child crystal symmetry combinations. The inherent versatility of the universally applicable parent grain reconstruction methods and the ability to conduct in-depth variant analysis are showcased via example workflows that can be programmatically modified by users to suit their specific applications. This is highlighted by three applications, namely �����-to-�� reconstruction in a lath martensitic steel, ��-to-�� reconstruction in a Ti alloy, and a two-step reconstruction from ����� to �� to �� in a twinning and transformation-induced plasticity steel. Advanced orientation relationship discovery and analysis options, including variant analysis, are demonstrated via the add-on function library ORTools.
