This study highlights the importance of exploring BiCrTe nanocomposites to uncover their distinctive properties and potential applications. Three samples were synthesized using hydrothermal methods by varying concentrations Bi Cr while maintaining a constant Te content. X‐ray diffraction (XRD) confirmed presence Bi₂Te₃ Cr₂Te₃ phases, supported transmission electron microscopy (TEM) observations. A reduction in content led smaller crystallite sizes. Raman spectroscopy revealed characteristic...
Compressive creep studies have been carried out on hot‐pressed ZrB 2 – SiC (ZS) and Si 3 N 4 (ZSS) composites in air under stress temperature ranges of 93–140 MPa 1300°C–1425°C, respectively for time durations ≈20–40 h. The results these shown the resistance ZS composite to be greater than that ZSS . As is increased from 1300°C 1425°C, exponent decreases 1.7 1.1, whereas drops 1.6 0.6. activation energies found as ≈95 ± 32 kJ/mol at temperatures ≤1350°C, ≈470 20 range 1350°C–1425°C. Studies...
Abstract In this study, aluminum-based metal matrix composites containing 5, 10, 15, 20, and 25% fly ash particles by weight have been fabricated using a stir casting route. Microstructural observations under an optical microscope suggest that in the cast are uniformly distributed throughout matrix. The mechanical properties such as tensile strength hardness of aluminum alloy enhanced significantly with addition ash. Wear behavior base its composite studied dry sliding conditions pin-on-disc...
A comparative study has been carried out on the mechanical properties at room temperature, thermal shock and ablation resistance as well oxidation behaviour of ZrB2-20SiC, ZrB2-20SiC-5Si3N4 ZrB2-20ZrC-20SiC-5Si3N4 (amounts represent volume percent) composites. Fracture toughness determined using either three-point bend tests single edge notch specimens, or by indentation technique. Addition Si3N4 sintering aid leads to enhancement in flexural strength fracture composite without ZrC. The...
The oxidation behavior of ZrB2-20 vol % SiC and SiC-5 Si3N4 composites prepared by hot-pressing subjected to isothermal exposure at 1200 or 1300 °C for durations 24 100 h in air, as well cyclic h, have been investigated. resistance the composite has found improve around 20%–25% with addition 5 during exposures °C. This improvement attributed formation higher amounts SiO2 Si2N2O, a greater amount continuity oxide scale, because these phases assist closing pores lower severity cracking...
In this investigation, the hypereutectic in-situ Al-X wt. %Mg2Si (X=15, 20, 25 and 30) composites have been developed through gravity casting technique with use of commercially pure Al, Si Mg metals. This composite comprises three phases, namely primary Mg2Si phase, which is formed during pseudo-eutectic transformation at time solidification engulfed by matrix (α-Al) binary eutectic (Al-Mg2Si) phase. Microstructure evaluation mechanical properties these has investigated. It observed that...
