Summary: Ti-22Al-26Nb and Ti-22Al-26Nb-5B compacts were processed using field assisted hot pressing (FAHP), with differences in processing temperatures and times resulting in varying microstructures. Higher processing temperatures led to fewer pores and three-phase microstructures, while longer processing times resulted in microstructural coarsening. Comparisons were made with compacts consolidated using hot isostatic pressing (HIP), showing finer grain sizes in the B-containing compacts. Compositional analysis suggested the presence of a B27 orthorhombic structure with B2TiNb stoichiometry in the Ti-22Al-26Nb HIP compact.Overall, FAHP was shown to be a viable powder metallurgy processing technique for Ti2AlNb-based intermetallic alloys.

Summary: This study investigates the use of hot isostatic pressing (HIP) to post-process additively manufactured continuous carbon fiber reinforced polyetheretherketone (PEEK) composites to improve their mechanical properties. The research found that increasing the HIP treatment temperature can reduce void content but excessive crystallinity may decrease the composite properties. The study suggests that HIP is a fast and robust method to enhance the performance of AM composites, while caution should be taken to avoid excessive crystallization during post-processing.

Summary: This study explores the consolidation process of W-CeO2 metal matrix composites with high CeO2 concentrations. The results show that decreasing the CeO2 concentration can increase the density and Vickers hardness of the composites. The oxidation state of CeO2 is a combination of Ce3+ and Ce4+, which is believed to contribute to the porosity of the composites. The hardness of the metal-oxide composite can be improved more than 2.5 times compared to pure W processed by the same route. This work provides processing guidelines for further consolidation of oxide-doped W composites.

Summary: The microstructural development and mechanical properties of tungsten heavy alloy (WHA) with a FeNiCoCrMn high entropy alloy (HEA) binder were investigated and compared to conventional WHA with a Fe-Ni binder. Both types of WHA were fabricated by hot isostatic pressing in an argon environment. The WHAs with HEA and conventional binders exhibited uniform and refined microstructures. The HEA binder showed a 42% increase in micro Vickers hardness values, and the tungsten heavy alloy fabricated with HEA binder also had higher hardness values. However, the WHA sample with HEA binder experienced faster strain hardening, premature failure, and lower ultimate strength and ductility.

Summary: This study investigated the fabrication of pure tungsten parts by laser powder bed fusion (LPBF) and its effect on the densification behavior, microstructural evolution, mechanical properties, and thermal conductivity. The results showed that the highest relative densities of 95.91% and 98.97% were achieved for the as-built and HIP treated samples, respectively. The mechanical testing results indicated that the highest microhardness of 450 HV and the maximum ultimate compressive strength of approximately 1.22 GPa were achieved in the specimen fabricated at a volumetric energy density (VED) of 312.50 J/mm3, under the conditions of as-built and HIPped at 1600 degrees C. The corresponding thermal conductivity was improved to 158 W/m.K after HIPping, suggesting its potential application in nuclear fusion reactors.

Summary: Hard/soft (H/S) SrEr0.01Cr0.01Fe11.98O19/NiFe2O4 magnetic nanocomposites with different H/S ratios were synthesized by one-pot sol-gel auto-combustion approach. XRD, SEM, TEM, and HR-TEM were used to characterize their structure and morphology. The magnetic properties were investigated via M-H and M-T measurements, revealing ferrimagnetic behavior and competition between intergranular exchange coupling and dipolar interactions. Microwave properties were examined and the ratio between soft and hard magnetic phases was found to affect electromagnetic absorption and reflection losses. The results suggest potential applications of such composites in electromagnetic absorbing materials.

Summary: The present study evaluates the possibility of constructing a new high-speed railway in Cairo, Egypt and assesses the geotechnical and environmental radiological hazards in the area. Geotechnical tests on soil samples show that the foundation level consists of poorly graded soil with varying liquid and plastic limits. The radioactive study reveals that the soil samples have activity concentrations within permissible limits. Based on the results, the soil in the studied area is deemed safe for construction and meets international standards. The construction of the railway also aligns with the requirements of the Kyoto Protocol, EU Climate and Energy policy, and other international treaties.

Summary: This study uses density functional theory to investigate the structural, electronic, optical, thermoelectric, and magnetic properties of A(3)In(2)As(4) and A(5)In(2)As(6) (A = Eu and Sr) Zintl phase compounds in orthorhombic phases. The results show agreement between the calculated structural properties and experimental data. The magnetic properties indicate that Sr3In2As4 and Sr5In2As6 are non-magnetic, while Eu3In2As4 and Eu5In2As6 are antiferromagnetic. Electronic properties reveal that all compounds are narrow direct bandgap semiconductors with r and M symmetry. The compounds exhibit optical dynamics in the infrared region and can be used as shields for ultraviolet radiation and in optoelectronic devices. Additionally, their low thermal conductivity, high Seebeck coefficient, and power factor suggest their potential for thermoelectric applications.

Summary: DFT was used in this study to investigate the electronic band profiles of CaCu3B2Re2O12 (B = Mn, Fe, Co, and Ni), and it was found that these compounds exhibit half-metallic character. The magnetic energy curves showed type-I ferrimagnetic order in all the compounds. The Cu-B, B-Re, and Cu-Re site spins interact through the Heisenberg model, resulting in the Cu(up arrow)B(up arrow)Re(down arrow) order. The Re moments anti-align with B and Cu, leading to ferrimagnetism.

Summary: The aim of this work was to investigate low temperature fast synthesis of cobalt spinel ferrite poly-crystalline ceramics. The combination of high temperature and high pressures was used to lower the threshold for activation of chemical interaction and increase the rate of diffusion kinetics, resulting in a sharp decrease in synthesis time. The study successfully synthesized test samples with significantly reduced duration and sintering temperature compared to conventional methods, and investigated the effects of thermobaric conditions on the properties of CoFe2O4 spinels.

Summary: In this study, a hydrothermal technique was used to incorporate a thin layer of WO3 onto PANI, forming a low-cost and efficient catalyst for the oxygen evolution process. The WO3-PANI demonstrated excellent electrocatalytic activity and durability, with higher current densities achieved at lower overpotentials. The integration of PANI increased the surface area and exposed more active spots for the oxygen evolution reaction, while WO3 and PANI synergistically contributed to the enhanced performance and stability of the catalyst.

Summary: The structural, electronic, elastic, and magnetic properties of the CeCu3-xMnxV4O12 (x = 0, 1, 2, and 3) system were investigated using DFT calculations with GGA, GGA+U, and HF potential. The results showed that the lattice parameters increased as Mn was substituted for Cu due to the larger atomic radii of Mn. CeCu3V4O12 was found to be the most thermodynamically stable compound. Substituting Mn for Cu led to the compounds becoming semi-metals and changing from non-magnetic to anti-ferromagnetic. The elastic characteristics demonstrated mechanical stability, anisotropy, and ductility in these compounds. The anti-ferromagnetic ductile nature of the Mn base compounds suggests their potential use in spintronic applications and magnetic cloaking devices.
