2023年4月25日 · In this report, XRD Peak broadening modeling was used for stimulating deformed systems of 3004 Al-alloys for determining the microstructure elements and confirmed with Rietveld MAUD profile analysis. The internal microscopic structural elements evolution of the distorted 3004 Al-alloys were examined using three XRD systems Scherrer, Williamson ...

2024年10月1日 · New processing techniques based on SR-XRD could be developed to improve the thermodynamic and kinetic properties of Mg-based alloys, such as mechanical milling of nanostructures, formation of nanocomposites, and electrochemical methods.

2019年7月23日 · Powder X-ray diffraction (XRD) is a common characterization technique for nanoscale materials. Analysis of a sample by powder XRD provides important information that is complementary to various microscopic and spectroscopic methods, such as phase identification, sample purity, crystallite size, and, in some cases, morphology.

2022年4月6日 · The X-ray diffraction (XRD) patterns of casted alloys in the form of ribbons and in-situ high-temperature XRD patterns were measured using Rigaku MiniFlex 600 X-ray...

2024年5月14日 · XRD is universally employed when new Ti alloys with unprecedented compositions are developed. Therefore, this work aims to highlight the advantages and limitations of using XRD for the ...

2024年11月29日 · Insights into the complex thermo-chemo-mechanical phenomena in AM through operando synchrotron XRD can be leveraged to guide alloy design and improve process control, ensuring that the...

2024年11月4日 · In this paper, we build prediction models for TC and ultimate tensile strength (UTS) of Al alloys using eXtreme gradient boosting (XGBoost) and support vector machine (SVM) algorithms, respectively. The models take physical descriptors from the alloy composition into account. Lasso and Gini Impurity algorithms were adopted for feature engineering.

2024年8月2日 · 1) 利用XRD表征304奥氏体不锈钢在低温循环塑性强化过程中的物相变化，发现经过强化处理后，304奥氏体不锈钢中形成了α′-马氏体颗粒。这种微观结构使金属材料在拉伸过程中实现了动态应变分配（dynamic strain partitioning）现象，提高了材料的整体力学性能。

2025年3月22日 · When the CuFe-NHPC/CNFs was acid-leached at 80 °C for 10 h, only a characteristic peak of graphitic carbon appears at around 26° in the XRD spectrum of the acid-leached sample, and no other metal peaks are detected (Fig. 6 g), suggesting that the CuFe alloys are etched off thoroughly, which can be further confirmed by TEM (Fig. S16).

2025年4月4日 · ABSTRACT. This study addresses the lack of systematic investigations on anisotropic thermal expansion in cold-rolled Al-2xxx alloys. A multi-technique approach combining dilatometry, Differential Scanning Calorimetry (DSC), Optical Microscopy (OM), and X-ray Diffraction (XRD) elucidates the coupled effects of cold rolling, recovery, recrystallization, and phase transformations along ...
