Abstract
Slip transmission across grain boundaries is an essential micromechanical processes during deformation of polycrystalline materials. Slip transmission processes can be characterized based on the geometrical arrangement of active slip systems in adjacent grains and the value of the critical resolved shear stress acting on the incoming and possible outgoing slip systems. We present a Matlab toolbox which enables quantification of grain boundary slip transfer properties and comparison with experiments. Using a graphical user interface, experimental grain boundary data can be directly exported as input files for crystal plasticity finite element simulation of bicrystal experiments.
Highlights
The micromechanical behavior of grain boundaries (GBs) is one of the key components in understanding heterogeneous deformation of metals [1]
Grain boundaries are color-coded to represent their maximum ′ value taking into account basal and prismatic 1st order 〈 〉-slip systems, which are of importance for slip transmission in such alloys [12]
By a combination of spherical indentation close to GBs with EBSD mapping, grain boundary slip transmission was characterized in Ti-5Al-2.5Sn
Summary
The micromechanical behavior of grain boundaries (GBs) is one of the key components in understanding heterogeneous deformation of metals [1]. An increasingly important issue in constitutive modeling is to include the GB micromechanical effects in order to improve the prediction of mechanical microstructure-property relationships [2]. To better understand the role played by the GBs and to quantify the GB micromechanics, a Matlab toolbox including graphical user interfaces (GUI) was developed [8]. This toolbox links experimental results to crystal plasticity finite element (CPFE) simulations
