Abstract

The aim of this study is to present a new physically based model capable of describing the deformation response of additively manufactured Ti-64 and contribute to the current knowledge in cast wrought (C&W) technology under various deformation conditions. The new proposed model was used to predict deformation behaviour, irrespective of the processing route, via linking relevant microstructural features with the strengthening mechanisms; grain shape, grain size, volume fraction and chemical composition for a wide range of deformation conditions (temperature and strain rate effects) suitable for studying hot forming and machining processes. Therefore, this study makes a major contribution to the understanding of processing routes in Ti-64. The new proposed model was implemented in a user subroutine VUMAT in commercial software Abaqus based on the Finite Element Method (FEM) and was compared with experimental data produce in this research and within literature.
