MTEX2Gmsh: a tool for generating 2D meshes from EBSD data

Recrystallization Behavior of Ti–6.5Al–3.5Mo–1.5Zr–0.3Si Alloy under Electroshocking Treatment

“…The grain boundaries are composed of an ordered sequence of indexed pixels after being processed by the Voronoi decomposition algorithm. [ 43–45 ]…”

“…The grain boundaries are composed of an ordered sequence of indexed pixels after being processed by the Voronoi decomposition algorithm. [43][44][45] Grain-boundary curvature к is used to characterize the mobility of grain boundaries regarding several pixelated levels, as shown in Figure 4i. The curvature at each position of the grain boundary varies, and the cumulative curvature value of each grain is an excellent descriptor to quantify grain-boundary irregularities.…”

PXO (Poly-XTAL Operations): MATLAB Codebase to Generate, Analyse and Export Complex 2D Spatio-Temporally Gradient Grain Structures

“…Poly-XTAL operations (PXO) is a MATLAB based computational platform which can enable users to create and prepare realistic grain structures for finite element analysis, simulate complex grain growth phenomenon and achieve spatiotemporal partitioning of a 2D space into a set of closed regions. In addition to various in-built tools, PXO generated grain structures can be imported into 3rd party open source libraries such as MTEX (Hielscher & Schaeben, 2008) and MTEX2Gmesh (Depriester & Kubler, 2020) to tend to the specific requirements of the user. It allows easy inclusion of user defined physics based models for grain growth.…”

“…PXO offers the added advantage of being able to be linked with MTEX (Hielscher & Schaeben, 2008) to deal with crystallographic texture calculations and advanced grain structure analysis. As PXO offers tools to export as many available temporal slices of grain structures as the user wishes, to a format able to be used in ABAQUS software for finite element analysis (using MTEX2Gmesh (Depriester & Kubler, 2020)), it offers a comparatively unique, viable and fast solution to researchers working in the field of Integrated Computational Materials Engineering (ICME) investigating structure-property-behaviour relationships. Additionally, PXO is able to combine this advantage with the ability to simulate grain growth in the presence of particles, particle clusters, fibres, whiskers and temperature fields.…”
