Title: Deformation behavior of HCP titanium alloy: Experiment and Crystal plasticity modeling

Abstract

The deformation behavior of commercially pure titanium is studied using experiments and a crystal plasticity model. Compression tests along the rolling, transverse, and normal-directions, and tensile tests along the rolling and transverse directions are performed at room temperature to study the activation of slip and twinning in the hexagonal closed packed titanium. A detailed EBSD based statistical analysis of the microstructure is performed to develop statistics of both {10-12} tensile and {11-22} compression twins. A simple Monte Carlo (MC) twin variant selection criterion is proposed within the framework of the visco-plastic self-consistent (VPSC) model with a dislocation density (DD) based law used to describe dislocation hardening. In the model, plasticity is accommodated by prismatic, basal and pyramidal slip modes, and {10-12} tensile and {11-22} compression twinning modes. Thus, the VPSC-MC model successfully captures the experimentally observed activation of low Schmid factor twin variants for both tensile and compression twins modes. The model also predicts macroscopic stress-strain response, texture evolution and twin volume fraction that are in agreement with experimental observations.

Role of microstructure on twin nucleation and growth in HCP titanium: A statistical study

Journal Article Arul Kumar, M. ; Wroński, M. ; McCabe, Rodney James ; ... - Acta Materialia

In this study, a detailed statistical analysis is performed using Electron Back Scatter Diffraction (EBSD) to establish the effect of microstructure on twin nucleation and growth in deformed commercial purity hexagonal close packed (HCP) titanium. Rolled titanium samples are compressed along rolling, transverse and normal directions to establish statistical correlations for {10–12}, {11–21}, and {11–22} twins. A recently developed automated EBSD-twinning analysis software is employed for the statistical analysis. Finally, the analysis provides the following key findings: (I) grain size and strain dependence is different for twin nucleation and growth; (II) twinning statistics can be generalized for the HCP metalsmore »« less

Characterization and modeling of mechanical behavior of single crystal titanium deformed by split-Hopkinson pressure bar

Journal Article Morrow, B. M. ; Lebensohn, R. A. ; Trujillo, C. P. ; ... - International Journal of Plasticity

Single crystal titanium samples were dynamically loaded using split-Hopkinson pressure bar (SHPB) and the resulting microstructures were examined. Characterization of the twins and dislocations present in the microstructure was conducted to understand the pathway for observed mechanical behavior. Electron backscatter diffraction (EBSD) was used to measure textures and quantify twinning. Microstructures were profusely twinned after loading, and twin variants and corresponding textures were different as a function of initial orientation. Focused ion beam (FIB) foils were created to analyze dislocation content using transmission electron microscopy (TEM). Large amounts of dislocations were present, indicating that plasticity was achieved through slip andmore »« less

A measure of plastic anisotropy for hexagonal close packed metals: Application to alloying effects on the formability of Mg

Journal Article Arul Kumar, Mariyappan ; Beyerlein, Irene Jane ; Tome, Carlos N. - Journal of Alloys and Compounds

Mg is inherently plastically anisotropic and, over the years, alloying development efforts have sought to reduce the plastic anisotropy in order to enhance formability. To understand the relationship between alloy type and plastic anisotropy, we use a visco-plastic self-consistent (VPSC) polycrystal plasticity model to relate the macroscopic constitutive response to the underlying slip and twinning mechanisms in pure Mg and several Mg alloys. In the calculations, the influence of alloy type is represented by the differences in the CRSS values among the basal, prismatic, pyramidal slip and tensile twin systems. We show that for the same initial texture, this microscopic-levelmore »« less

Experimental verification of a crystal plasticity-based simulation framework for predicting microstructure and geometric shape changes: Application to bending and Taylor impact testing of Zr

Journal Article Vasilev, Evgenii ; Zecevic, Miroslav ; Mccabe, Rodney James ; ... - International Journal of Impact Engineering

This paper is concerned with experimental verification of a recently developed multi-scale simulation framework for plastic deformation of metallic materials from quasi-static to impact deformation conditions. The framework is a visco-plastic self-consistent (VPSC) polycrystalline model embedded in an implicit finite element method (FE-VPSC) to provide a microstructure-sensitive constitutive response at each material point. Each material point of the FEM model is a polycrystalline aggregate with crystallographic deformation mechanisms operating at the single crystal scale with their evolving activity based on a dislocation density-based hardening law and texture.

The influence of bi-metal interfaces on deformation mechanisms in bulk nanolaminar composites

Conference Mara, Nathan Allan ; Ledonne, Jon ; Wynn, Thomas A ; ...

In this presentation, we report on the plastic deformation mechanisms in Ag-Cu and Cu-Nb nanocomposites rolled to large reductions. Starting with an Ag-Cu alloy with eutectic lamellar bilayer thickness of 200 nm, we roll the as-cast rods from 9.5 mm diameter to sheets of final thickness varying from 2.4 mm to 500 {micro}m, corresponding to 75% to 95% nominal reduction in thickness. Cu(111) X-ray pole figures of the rolled nanocomposites indicate a measured texture similar to that of Ag but different from that expected during rolling of pure bulk Cu involving dislocation slip alone.
