Jun 22, 2020 · In the present study, X-ray diffraction was applied to measure stacking fault energy of Cr–Ni austenitic steels containing different amounts of alloying elements. The results in austenitic steels show that the Ni content and Cr/Ni ratio have a strong effect on SFE.

Mar 2, 2023 · The existence of an HCP phase in FCC-type high-entropy alloys can improve the alloy’s mechanical properties. In many cases, an HCP phase is induced by deformation. In the present work, an FCC to HCP transition was detected during the cooling of Co1.5CrFeMnNi0.5 and Co1.75CrFeMnNi0.25 alloys.

Dec 1, 2020 · New face-centered cubic (FCC) multicomponent alloys designed through the high-entropy (HEA) concept and strengthened with L1 2 ordered precipitates are promising material solutions for high temperature (HT) structural applications.

Apr 1, 2022 · Based on this knowledge, the present work aims to: (1) process chemically homogeneous, single-phase FCC CrMnFeCoNi HEAs with different Cr/Ni ratios and recrystallized microstructures; (2) experimentally assess composition-dependent physical properties of these alloys including their dilatation behavior, elastic and magnetic properties, and SFEs;...

Nov 15, 2015 · The effect of milling time on defect structure and phase composition of nanostructured Fe–25Cr–10Mn–1N (wt%) alloy powders processed by mechanical alloying (MA) in the high energy planetary ball mill under argon atmosphere was investigated using X-ray diffraction (XRD) and Mössbauer spectroscopy.

Bond charges in covalent solid (1/8,1/8,1/8), (3/8,3/8,1/8),(1/8,3/8,3/8) and (3/8,1/8,3/8). Bond charges form a "crystal" with a fcc lattice with 4 "atoms" per unit cell. origin : (1/8,1/8,1/8). …

Sep 1, 2024 · In this paper, we report the results of the preparation and crystallization of CrCoNi-based amorphous alloys. We evaluated the chemical ordering developed in a crystallized fcc solid solution through anomalous X-ray scattering (AXS) and scanning transition electron microscopy (STEM) observations of the microstructure of crystalline phases. 2.

A combinatorial Co-Cr-Fe-Ni compositional complex alloy (CCA) thin film disk with a thickness of 1 µm and a diameter of 10 cm was processed by multiple-beam-sputtering physical vapor...

In the present study, X-ray diffraction was applied to measure stacking fault energy of Cr–Ni austenitic steels containing different amounts of alloying ele-ments. The results in austenitic steels show that the Ni content and Cr/Ni ratio have a strong effect on SFE.

May 26, 2023 · The influence of Cr doping on the phase structure, microstructure, and magnetic properties is thoroughly investigated through X-ray difraction (XRD), scanning electron microscopy (SEM), and vibrating sample magnetometry.
