Bounds To Texture Components In Superposed Crystallographic Textures

Journal of the American Ceramic Society, 2006
Crystallographic texture generates anisotropy that is essential to many advanced ceramic applications. For microstructures where texture components have resulted from unique material processes, the measured texture is a superposition of these independent texture components, making it difficult to characterize these unique processes

Structure and Crystallographic Texture of Arthropod Bio-Composites

Materials Science Forum, 2005
In this study we present experimental investigations on the microscopic structure, constituent phases, and crystallographic textures of the exoskeleton of three types of decapod crustaceans, namely, lobster, crab, and horseshoe crab. The carapace of such animals is a biological multiphase nano-composite consisting of an organic matrix (crystalline ...

Crystallographic texture of stress-affected bainite

Proceedings of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2007
A method is presented for calculating both the macroscopic strains and the crystallographic bias which develop when a polycrystalline sample of austenitic steel is transformed into bainite or martensite under the influence of an applied stress or a system of stresses.

Crystallographic texture and grain growth

Materials Letters, 2019
Abstract By means of numerical modelling it is for the first time shown that the mobility anisotropy of grain boundaries has a strong influence on texture alterations and microstructure development.

Crystallographic Texture and Plastic Anisotropy

2016
The structure of crystalline materials can be characterized by four structure levels: 1. Crystal Structure specifies the kind and position of atoms in the unit cell of the ideal crystal lattice. 2. Phase Structure specifies the sizes, shapes and mutual arrangement of single-phase volumes (volumes with constant crystal structure).

Quantitative comparison of measured crystallographic texture

Journal of Applied Crystallography, 2016
A new approach for the determination of a quantitative measure to compare pole figures for different specimens is presented. The suggested approach is based on the Kolmogorov–Smirnov test. A new quantitative similarity measure between the textures of different specimens is suggested.

Crystallographic Texture Measurement and Analysis

1986
Abstract Crystallographic texture measurement and analysis is an important tool for correlating material properties with microstructural features. This article describes the general approach to quantifying crystallographic texture, namely, the collection of statistical data from grain measurements and subsequent analysis based on Euler ...

Evolution of crystallographic texture in thin wires

Journal of Applied Crystallography, 1992
An X-ray diffraction procedure has been developed to measure accurately the textures of thin wires so that the texture variation across the wire radius may be obtained. Since X-rays penetrate no further than the surface of most metals, X-ray examination can be considered to be superficial for large wires but by thinning the wire it is possible to ...

Mollusc shell microstructures and crystallographic textures

Journal of Structural Geology, 2000
Abstract X-ray diffraction is used to characterise textures of the aragonite layers of shells from monoplacophoras, bivalves, cephalopods and gastropods. Textures vary in strength, pattern and through the thickness of the shells. The texture patterns exhibited in the studied taxa, which can be quantitatively described by a limited number of ...

Evolution of Crystallographic Texture and Strength in Beryllium

AIP Conference Proceedings, 2004
The evolution of the dynamic mechanical behavior and crystallographic texture in polycrystalline beryllium with different initial textures was measured and compared to a polycrystalline plasticity model. The split‐Hopkinson pressure bar compression behavior and the activity of deformation mechanisms were found to be highly dependent on the initial ...
