Perovskite materials are used extensively in the area of material science for theoretical computations. Density functional theory (DFT) calculations are used in this study to determine the properties of the cubic halide perovskite LaMnX3 (X = Cl, Br, and I). These compounds contain PM3M-221 space groups and a cubic structure. They were created via the Cambridge serial total energy package (CASTEP) program, which also used HSE (Heyd-Scuseria-Ernzerhof) exchange-correlation functionals. The structural, electrical, optical, and mechanical characteristics of the compounds are determined.LaMnCl3, LaMnBr3, and LaMnI3all have direct bandgaps of 2.366 eV, 1.844 eV, and 1.579 eV, respectively, based on their structural characteristics. Total and partial densities of states (TDOS and PDOS) offer proof of the degree of electron localization in specific bands. Electronic studies indicate that LaMnX3 materials (X = Cl, Br, I) are semiconductors. The dielectric function's extensive range of energy transparency can be seen in the imaginary element dispersion. LaMnCl3 compound's absorption and conductivity are preferable to those of LaMnBr3 and LaMnI3, improving its applicability for Optoelectronic applications and work function. We found that the cubic structures of all three compounds allow them to be mechanically stable. The calculated elastic results also satisfy the compound's mechanical strength requirements. Such materials are used in optoelectronic applications.

An experimental study of three body abrasive wear behaviour of AZ31/15 vol.% Zirconium dioxide (ZrO2) reinforced composites prepared by stir casting has been carried out. Microstructural analysis of the developed composites was carried out and found out that the microstructure of the composites revealed a uniform distribution of ZrO2 particles with refinement in the grain size of the matrix from 70 to 20 µm. The alterations in the microstructure led to an enhancement in both hardness (68–104 HV) and tensile strength (156–236 MPa) due to Orowan strengthening, quench hardening effect and better bonding. Response surface methodology was applied to formulate the three-body abrasive wear test characteristics such as load, speed, and time. Three body abrasive test results were utilized to generate surface graphs for different combinations of wear test parameters revealed an increase in specific wear rate. The specific wear rate was observed to increase with increase in speed up to a certain level and then started to decrease. The lowest possible specific wear rate was obtained for an optimized load of 20 N and a speed of 190 ms−1. Scanning electron microscopic examination of wear-tested samples showed higher specific wear rate at higher loads with predominantly abrasion type material removal. In conclusion, this study makes a substantial contribution to the field by elucidating the complex relationships among microstructure, mechanical properties, and the three-body abrasive wear behavior of AZ31/ZrO2 composites. The determination of optimal wear conditions and the insights gained into wear mechanisms provide valuable information for designing materials, implementing engineering solutions, and advancing the creation of wear-resistant components across a range of industries.

“…[16][17][18] Containing continuous metal wires with diameters of 0.05-0.3 mm prepared by series of specific processes, MR exhibits superior adaptability to harsh working environments such as high temperatures (up to 600 °C) and low temperatures (as low as À70 °C), space radiation, and corrosion when compared to conventional polymeric damping materials. [19] The 3D continuous network structure of MR provides a controllable and stable reinforcement phase distribution in metal matrix composites, exerting a strengthening effect on the metal matrix.

High‐performance lightweight composites are developed by integrating metal rubber (MR) into a zinc alloy (ZA8) matrix via squeeze casting. MR, comprising 304 stainless steel wires with diameters of 0.15 mm, forms three‐dimensional network skeletons with volume fractions of 8.8 vol.% (S1), 11.1 vol.% (S2), and 13.4 vol.% (S3), respectively. The preparation parameters of the composites are optimized, and their micro‐hardness is investigated. Special attention is paid to the ultimate compression and shear performance at 25 °C, 150 °C, and 250 °C. The microstructure and failure analysis are performed via SEM. The results reveal a 48.0% increase in micro‐hardness at composite interfaces relative to ZA8. At 25 °C, S2 possesses an ultimate compressive strength (UCS) of 401.4 MPa, which is 33.7% higher than that of ZA8. At 150 °C and 250 °C, S3 exhibits UCS values of 180.3 MPa and 74.3 MPa, exceeding those of ZA8 by 61.7% and 110.5%, respectively. Meanwhile, the ultimate shear strength of composites slightly drops below that of the matrix: the corresponding value of S1 specimen (158.4 MPa) at 250°C is 11.5% below that of ZA8. Therefore, compression and shear failure mechanisms of MR/ZA8 composites are quite intricate, involving SSW separation, necking, and ZA8 fractures.This article is protected by copyright.
