“…Other MAX phases include 312 and 413 of Ti 2 AlC ( Rampai and Tokoloho, 2011 ; Galvin et al, 2018 ; Gao et al, 2020 ; Poulou et al, 2021 ). The synthesis of the Cr 2 AlC MAX phase involves various methods such as the molten salt method ( Abdelkader, 2016 ), ball milling ( Ta et al, 2021 ; Mansouri et al, 2023 ), chemical vapor deposition (CVD) ( Gorshkov et al, 2017 ), Physical vapor deposition (PVD) ( Rueß et al, 2021 ; Li et al, 2024 ) and, notably, the sol-gel method. In the previous literature, the sol-gel method was utilized to fabricate the Cr 2 GaC MAX phase ( Siebert et al, 2019 ).…”

MAX phases, characterized as nanolaminates of ternary carbides/nitrides structure, possess a unique combination of ceramic and metallic properties, rendering them pivotal in materials research. In this study, chromium aluminum carbide ternary compounds, Cr2AlC (211), Cr3AlC2 (312), and Cr4AlC3 (413) were successfully synthesized with high purity using a facile and cost-effective sol-gel method. Structural, morphological, and chemical characterization of the synthesized phases was conducted to understand the effects of composition changes and explore potential applications. Comprehensive characterization techniques including XRD for crystalline structure elucidations, SEM for morphological analysis, EDX for chemical composition, Raman spectroscopy for elucidation of vibrational modes, XPS to analyze elemental composition and surface chemistry, and FTIR spectroscopy to ensure the functional groups analysis, were performed. X-ray diffraction analysis indicated the high purity of the synthesized Cr2AlC phase as well as other ternary compounds Cr3AlC2 and Cr4AlC3, suggesting its suitability as a precursor for MXenes production. Additionally, the antimicrobial activity against Candida albicans and biocompatibility assessments against Escherichia coli (E. coli), Staphylococcus aureus (S. aureus), and HepG2 cell line were investigated. The results demonstrated significant antifungal activity of the synthesized phases against Candida albicans and negligible impact on the viability of E. coli and S. aureus. Interestingly, lower concentrations of Cr2AlC MAX phase induced cytotoxicity in HepG2 cells by triggering intercellular oxidative stress, while Cr3AlC2 and Cr4AlC3 exhibited lower cytotoxicity compared to Cr2AlC, highlighting their potential in biomedical applications.

This study focuses on the role of Cr2AlC‐MAX phase incorporation on the density, phase composition, microstructure, and mechanical properties of 90W‐6Ni‐2Fe‐2Co heavy alloy. The blended powders are ball milled in a high‐energy ball mill up to 40 h, compacted, and sintered at 1500 °C. The mechanical alloying results in a refined microstructure with uniform distribution of W, matrix, and dispersoids. The minimum grain size of W (14.7 ± 5.6 μm) is obtained in 2 wt% Cr2AlC‐containing tungsten alloy prepared from 40 h‐milled powders. Among the investigated alloys, 1 wt% Cr2AlC‐incorporated samples exhibit maximum compressive stress (2026 MPa). The incorporation of fine Cr2AlC as dispersoids is found to be beneficial in improving the strength as well as ductility of WHAs. The best combination of yield strength (553.4 MPa), ultimate tensile strength (1011.2 MPa), ductility (11.4%), and product of strength and elongation (11.5 GPa%) is found in alloy prepared from 40 h milled 90W‐4.8Ni‐1.6Fe‐1.6Co‐2Cr2AlC. The improved tensile strength in Cr2AlC‐incorporated WHAs may be attributed to the combined effect of grain size refinement and dispersion strengthening. Overall, the combination of ball milling and Cr2AlC incorporation in tungsten‐heavy alloys is found to be effective in developing a novel W‐based alloy system for strategic applications.
