摘要

多晶衍射是一种用于评估晶体成分内部弹性应变的可靠方法。在使用 Debye-Scherrer 二维 X 射线衍射环量化弹性应变的传统方位角分割(Caking)方法之外,扩展 Caking(exCaking)方法代表了这一方法的进步。所提出方法的前提是,每个完整的衍射环都包含入射光束法线平面上完整弹性应变变化的全面信息,因此可以引入一种新颖的算法,利用椭圆几何对具有完整角度变化的 Debye-Scherrer 衍射环进行分析,即使偏心值较小也能确保精确度,并提供更高的总体精确度。通过控制台应用 exCaking 方法,可以根据项目资料库中提供的最新规则对多晶 X 射线衍射数据进行精确分析。本研究通过数值和经验检验以及误差分析,证实了该方法的可靠性和准确性。本研究还介绍了一个具体的验证案例研究,分析了 Ti-6Al-4V 钛合金棒材通过四点弯曲发生塑性变形时的力平衡残余弹性应变分布。

Extended Caking Method for Strain Analysis of Polycrystalline Diffraction Debye–Scherrer Rings
Polycrystalline diffraction is a robust methodology employed to assess elastic strain within crystalline components. The Extended Caking (exCaking) method represents a progression of this methodology beyond the conventional azimuthal segmentation (Caking) method for the quantification of elastic strains using Debye–Scherrer 2D X-ray diffraction rings. The proposed method is based on the premise that each complete diffraction ring contains comprehensive information about the complete elastic strain variation in the plane normal to the incident beam, which allows for the introduction of a novel algorithm that analyses Debye–Scherrer rings with complete angular variation using ellipse geometry, ensuring accuracy even for small eccentricity values and offering greater accuracy overall. The console application of the exCaking method allows for the accurate analysis of polycrystalline X-ray diffraction data according to the up-to-date rules presented in the project repository. This study presents both numerical and empirical examinations and error analysis to substantiate the method’s reliability and accuracy. A specific validation case study is also presented to analyze the distribution of residual elastic strains in terms of force balance in a Ti-6Al-4V titanium alloy bar plastically deformed by four-point bending.

期刊介绍: Crystals (ISSN 2073-4352) is an open access journal that covers all aspects of crystalline material research. Crystals can act as a reference, and as a publication resource, to the community. It publishes reviews, regular research articles, and short communications. Our aim is to encourage scientists to publish their experimental and theoretical results in as much detail as possible. Therefore, there is no restriction on article length. Full experimental details must be provided to enable the results to be reproduced. Crystals provides a  forum for the advancement of our understanding of the nucleation, growth, processing, and characterization of crystalline materials. Their mechanical, chemical, electronic, magnetic, and optical properties, and their diverse applications, are all considered to be of importance.
