Special Issue Information

Dear Colleagues,

Metal forming/processing involves a series of thermo-mechanical deformations. Hierarchical structured materials develop during processing, which determines the final metal’s properties. An efficient approach to accelerate material development is to establish the Process–Structure–Property (PSP) linkages. This is beneficial to forward property prediction, which also enables finding optimal architected structures for given target properties in inverse material design. In addition, it accelerates the design, characterisation, evaluation, and deployment of metals.

Physics-based modelling has become an effective and efficient tool in material development due to increased computational resources, improved numerical algorithms, and progressed physical models. The application of machine learning and big data in materials science is unveiling hidden PSP relationships and can be harnessed in inverse design, e.g., optimizing processing and discovering materials. Combining materials informatics with computational materials science enables the closed-loop study of materials science, where computational materials science generates datasets and material informatics guides simulations.

This Special Issue aims to cover the latest advances in establishing PSP linkages using physics-based computational material science and machine learning methods. In this regard, original research papers, short communications, and review articles studying the following subjects are welcome in this Special Issue: metal forming/processing; microstructure characterisation; computational material science; machine learning; and data-driven materials design.

Abstract
Texture evolution during accumulative roll-bonding (ARB) is complicated because of the change in the through-thickness position that results from repeated cutting–stacking and roll-bonding.

Texture evolution during accumulative roll-bonding (ARB) is complicated because of the change in the through-thickness position that results from repeated cutting–stacking and roll-bonding. In this study, a macro–micro two-scale modeling was carried out to investigate the behaviors of texture evolution during ARB. The finite element method (FEM) was used to predict the strain history at a macro-scale, while a crystal plasticity FEM was used to reproduce the texture at a micro-scale. The texture evolution along three different cutting–stacking paths was traced and investigated. The patterns of texture transition between the rolling-type, shear-type, and random-type textures were studied by using area fractions of texture components, the distribution of textures, and the distribution of crystal rotation angles.

Body-centered cubic bismuth (Bi) is considered to be an enticing pressure marker, and, therefore, it is highly desirable to command its accurate equation of state (EOS). However, significant discrepancies are noted among the previous experimental EOSs. In the present work, an EOS of up to 300 GPa is theoretically obtained by solving the partition function via a direct integral approach (DIA). The calculated results nearly reproduce the hydrostatic experimental measurements below 75 GPa, and the deviations from the measurements gradually become larger with increasing pressure. Based on the ensemble theory of equilibrium state, the DIA works with high precision particularly in high-pressure conditions, so the hydrostatic EOS presented in this work is expected to be a reliable pressure standard.
