Abstract

The application Sinpol, a novel tool for neutron transmission data analysis, is used to simulate the effect of deformation and recrystallization crystallographic textures in fcc materials. The texture is characterized using an orientation distribution function (ODF), which describes the distribution of crystal orientations over the three-dimensional orientation space. The Sinpol code combines the transmission contribution of each single crystal grain in the ODF to generate neutron transmission patterns through a polycrystalline aggregate. A series of texture components, commonly found in fcc materials, are considered and their neutron transmission calculated for further analysis of experimental data. The effect of grain statistics is investigated and the simulation results on more complex ODF textures are also presented. Finally, the neutron transmission simulations are successfully benchmarked on experimental data recorded on an additive manufactured Inconel 718 specimen.

Applying neutron transmission physics and 3D statistical full-field model to understand 2D Bragg-edge imaging

Journal Article Xie, Qingge ; Song, Gian ; Gorti, Sarma B. ; ... - Journal of Applied Physics

Bragg-edge imaging, which is also known as neutron radiography, has recently emerged as a novel crystalline characterization technique. Modelling of this novel technique by incorporating various features of the underlying microstructure (including the crystallographic texture, the morphological texture, and the grain size) of the material remains a subject of considerable research and development. In this paper, Inconel 718 samples made by additive manufacturing were investigated by neutron diffraction and neutron radiography techniques. The specimen features strong morphological and crystallographic textures and a highly heterogeneous microstructure. A 3D statistical full-field model is introduced by taking details of the microstructure into accountmore »« less

Evolution of texture during thermo-mechanical processing of an Al-Mg-Si-Cu alloy

Journal Article Singh, R K ; Singh, A K - Scripta Materialia

Heat-treatable 6000-series alloys are currently used in selected automotive skin components, and are being considered in further applications towards reducing the weight of automobiles and aircrafts. Despite the advantage in terms of strength to weight ratio, these alloys exhibit lower forming limits. The microstructural characteristics produced during recrystallization, such as grain structure and crystallographic texture, play a dominant role in controlling the mechanical properties and formability of sheet in the T-4 condition. Crystallographic texture plays an important role in forming of materials, as it controls the plastic anisotropy like wall thickness reduction (R-value) and earring properties. It is, therefore, importantmore »« less

Grain boundary distributions, texture and orientation correlations in austenitic stainless steels

Journal Article Gertsman, V Y ; Russian Academy of Sciences, Ufa ; Tangri, K - Scripta Metallurgica et Materialia

Among various distribution functions describing microstructure of polycrystals, two relate to the crystallite orientations, namely, crystallographic texture and misorientation distribution. Complications arise due to the orientation correlations which may exist between various crystallites of the polycrystalline aggregate. These two factors, viz. texture and orientation correlations, determine the grain boundary distribution in a sample. Contributions of these factors to the misorientation distribution as a whole and to the fractions of specific grain boundary types are yet to be fully understood. Studies have shown that in some materials grain boundary distribution is primarily determined by texture, whereas the orientation correlations may playmore »« less

Growth textures of thick sputtered films and multilayers assessed via synchrotron transmission Laue

Journal Article Vill, M A ; Rek, Z U ; Yalisove, S M ; ... - Journal of Applied Physics

The growth textures of {ital thick} sputtered Mo metallizations and Mo/W multilayers, were characterized via a synchrotron white-beam (WB) x-ray transmission Laue technique. Transmission x-ray diffraction studies of Mo specimens up to 61 {mu}m thick were performed with WB synchrotron radiation; while the practical thickness limit for similar observations using a conventional laboratory Cu {ital K}({alpha}) x-ray source is ten times smaller. This unique approach used polychromatic x rays to simultaneously produce diffraction from a wide spread of orientations of many crystallographic planes for all the grains within a relatively large specimen volume ({approx}60{times}10{sup 6} {mu}m{sup 3}). These patterns weremore »« less

Coupled Simulations of Texture Evolution during Deformation and Recrystallization of FCC and BCC Metals

Journal Article Radhakrishnan, Balasubramaniam ; Gorti, Sarma B - Materials Science and Engineering A

Thermo-mechanical processing to produce optimum grain structure and texture is key to the successful utilization of commercial aluminum alloys and steels as sheet products. Several modeling techniques have been developed in the past with a reasonably good predictive capability for bulk deformation textures. However, prediction of texture evolution during recrystallization remains very challenging because of uncertainties involved in predicting the mechanisms that lead to nuclei formation and crystallographic orientations of the nuclei, and the uncertainties involved in predicting the grain boundary properties that determine the growth kinetics of the nuclei. We present some of our recent work in modeling themore »« less
