Title: Microstructure and mechanical properties of Ti–6Al–4V: Mill-annealed versus direct metal laser melted alloys

Abstract

Additive manufacturing processes such as direct metal laser melting (DMLM) are known to produce highly anisotropic microstructures. The present work compares the microstructure and mechanical properties of DMLM Ti–6Al–4V with that of mill-annealed alloys. Results show that the yield and hardening response of DMLM Ti–6Al–4V does not depend on the testing direction relative to the build direction, while the response of mill-annealed Ti–6Al–4V strongly depends on the testing direction. In conclusion, these results are discussed in light of the microstructure, texture, and polycrystal plasticity modeling.

The influence of mechanical constraints introduced by β annealed microstructures on the yield strength and ductility of Ti-6Al-4V

Journal Article Kasemer, Matthew ; Quey, Romain ; Dawson, Paul - Journal of the Mechanics and Physics of Solids

Discussed is a computational study of the influence of the microstructure’s geometric morphology on the yield strength and ductility of Ti-6Al-4V. Uniaxial tension tests were conducted on physical specimens to determine the macroscopic yield strength and ductility of two microstructural variations (mill annealed and β annealed) to establish comparisons of macroscopic properties. A multi-experimental approach was utilized to gather two dimensional and three dimensional data, which were used to inform the construction of representative β annealed polycrystals. A highly parallelized crystal plasticity finite element framework was employed to model the deformation response of the generated polycrystals subjected to uniaxial tension.more »« less

Modeling the role of local crystallographic correlations in microstructures of Ti-6Al-4V using a correlated structure visco-plastic self-consistent polycrystal plasticity formulation

Journal Article Riyad, Iftekhar A. ; Feather, William G. ; Vasilev, Evgenii ; ... - Acta Materialia

This paper presents a multi-level crystal plasticity-based simulation framework for modeling mechanical response and microstructure evolution of Ti-6Al-4V with α-lath/lamellar microstructures. Here, the model is a correlated structure visco-plastic self-consistent (CS-VPSC) formulation linking three scales: a single crystals micro-scale, a lath/lamellar colony meso-scale, and a lath/lamellar aggregate macro-scale. A selected hardening law for the evolution of critical resolved shear stress per slip system used in CS-VPSC is phenomenological. However, it adjusts the resistances of basal and prismatic slip systems based on the geometry of slip transfer between adjacent lamellae. Consistent with experimental evidences, the resolved shear stress on the pyramidalmore »« less

Using machine-learning to understand complex microstructural effects on the mechanical behavior of Ti-6Al-4V alloys

Journal Article McElfresh, Cameron ; Roberts, Collin ; He, Sicong ; ... - Computational Materials Science

Structural materials properties are highly dependent on their microstructure. Their microstructure is in turn affected by multiple fabrication and thermo-mechanical treatment parameters, all of which conform a highly-dimensional parametric space with often hidden correlations that are difficult to extract by experimentation alone. This is particularly true for alloys of the dual-phase Ti-6Al-4V family, with their greatly complex and rich microstructures, which combine several intrinsic length scales associated with multiple grain and subgrain structures, grains with different crystal lattices (α and β phases), and complex chemistry. In this paper we use a comprehensive set of machine learning techniques to develop predictivemore »« less

Technical Report Gilmore, C M ; Imam, M A

In part '2' of the report, the Fatigue crack initiation lives are determined for three annealed microstructures of Ti-6Al-4V: alpha-beta annealed, recrystallized anneal and beta anneal. The tests were conducted using fully reversed cyclic torsional strain amplitudes of plus or minus 0.006 and plus or minus 0.012. At both strain amplitudes the alpha-beta annealed alloy had the longest fatigue life and the beta annealed alloy had the shortest fatigue life. In part 'b', the fatigue life of annealed and quenched microstructures of the alloy Ti-6Al-4V were determined using a fully reversed cyclic torsional strain of 0.02. The quenched microstructures allmore »« less
Fatigue crack growth mechanisms at the microstructure scale in as-fabricated and heat treated Ti-6Al-4V ELI manufactured by electron beam melting (EBM)

Journal Article Galarraga, Haize ; Warren, Robert J. ; Lados, Diana A. ; ... - Engineering Fracture Mechanics

Electron beam melting (EBM) is a metal powder bed fusion additive manufacturing (AM) technology that fabricates parts by selectively scanning consecutive powder layers with an electron beam. Additive manufacturing technologies are increasing in importance for aerospace and medical applications, where the demand for a fundamental understanding and predictability of static and dynamic material properties are high. Ti-6Al-4V is the most widely used and studied alloy for this technology, and is the focus of this work in its Extra Low Interstitial (ELI) variation. The layered manufacturing of metallic components by EBM creates a unique directional microstructure, and consequently, anisotropic properties. Microstructuremore »« less
