Achieving basal texture in pure titanium: Process implementation and mechanical property evaluation

Mélaine Tournay, Jean‐Sébastien Lecomte, Christophe Schuman, Yudong Zhang et autres

The strong crystallographic texture in titanium sheets leads to anisotropic mechanical properties, complicating forming processes. In this article, we outline a straightforward industrial thermomechanical process to achieve a basal texture in commercially pure titanium. This process involves cold rolling followed by annealing, …

Critical Resolved Shear Stress and Work Hardening Determination in HCP Metals: Application to Zr Single Crystals

Jean‐Sébastien Lecomte, Jérôme Crépin, Pierre Barbéris

Obtaining precise parameters of deformation modes remains a significant challenge in materials science research. Critical resolved shear stresses (CRSS) and work hardening, particularly in hexagonal metals, are crucial parameters for constitutive laws in crystal plasticity. This paper presents a novel approach to …

Robust determination of cubic elastic constants via nanoindentation and Bayesian inference

Yazid Janati El Idrissi, Thiebaud Richeton, Damien Texier, Stéphane Berbenni et autres

Nanoindentation is a promising tool for advancing the estimation of single crystal elastic constants in multiphase materials. In this study, a novel protocol is presented that couples high-speed nanoindentation mapping with the Vlassak and Nix’s model and Bayesian inference simulations to statistically …
