What is the reason of the formation of the needle-like, rod-like mophology of Cr2Ti, the laves phase?
Best insight from top research papers
The needle-like, rod-like morphology of Cr2Ti, the Laves phase, is primarily attributed to microstructural features and alloy compositions. Studies have shown that the addition of Ti in Cr2Nb-based alloys promotes the toughening of Laves phase structures, leading to the formation of eutectic microstructures that enhance fracture toughness . Furthermore, the distribution of alloying elements in Cr2Nb-based high-temperature alloys plays a crucial role in improving the volume fraction of Cr2Nb in the alloy tissue, thereby influencing the morphology of the Laves phase and enhancing mechanical properties and thermal stability . Additionally, the formation of Ti-Cr compounds, including the intermetallic Laves phase TiCr2, can be induced by high fluence implantations of chromium ions in pure titanium, with implantation temperature and temporal coincidence being key factors for phase formation .

What is the melting temperature of Fe-Cr alloy?4 answersThe melting temperature of Fe-Cr alloys varies depending on the specific composition. For example, Fe-4Cr and Fe-16Cr nanocrystalline alloys exhibited different oxidation behaviors at temperatures above 700°C, with distinct oxide morphologies observed. In another study, the Fe-rich border of the metastable miscibility gap (MMG) in Fe-Cr alloys was determined to be around 24.5 at.% Cr, with the solubility limit of Cr in iron estimated to be approximately 20.3 at.% Cr at 858 K. Additionally, the presence of limited amounts of Cr in Fe did not significantly alter the melting curve of Fe, with Fe-11Ni-18Cr alloy melting at around 4100-5500 K at pressures relevant to the Earth's core.
What is the speciality of ferromagnetism in Cr based monolayers?4 answersFerromagnetism in Cr-based monolayers is a special characteristic that makes them suitable for spintronic applications. The Cr atom doping in InS monolayers induces ferromagnetism and improves their electronic and magnetic properties, making them potential candidates for spintronic devices. Similarly, the Janus Cr2AsP monolayer exhibits intrinsic ferromagnetism and can be tuned to FM half-metallicity through Se doping, offering important implications for spintronic device preparation. The CrXY monolayers (except CrOI) are stable and ferromagnetic semiconductors, with the coupling strength enhanced by the nature of Cr-X bonds, making them feasible for 2D spintronic devices. Additionally, CrI3 monolayers doped with 3d transition-metal atoms show tunable electronic properties, improved ferromagnetic stabilities, and FM-to-AFM transitions, expanding the potential application perspectives of CrI3 monolayers in spintronics.
How does Co doping affect the electronic structure of L10-FeNi?4 answersCo doping in L10-FeNi enhances the magnetocrystalline anisotropy (MCA) and improves the potential of L10-FeNi as a permanent magnetic material. The electronic and magnetic properties of pristine and Pt-doped FeNi were investigated, and it was found that Pt-substitutional doping increases the MCA of FeNi while maintaining saturation magnetization. The introduction of tetragonal distortion through interstitial C-doping also results in a large MCA in FeNi, making it a potential rare-earth free permanent magnetic material. The crystal orientation of FeNiN films strongly affects the long-range order parameter and MCA of L10-FeNi films after denitridation. The formation of L10-FeNi is influenced by the strain caused by rapid thermal annealing, leading to the formation of L10-ordered clusters in a disordered phase.
What material is used in larprascopic devices?5 answersLaparoscopic devices use a variety of materials. One such material is a thermoplastic called polycarbonate polyurethane, which is used as the core material in the manufacturing of artificial meniscus prosthetic devices. Another material used in laparoscopic devices is amorphous, thermoplastic polymethyl methacrylate (PMMA), which forms a matrix layer in orthopedic devices. This material can be shaped and reshaped by heating it to less than 200°C, making it suitable for self-supporting, shell-like structures in orthopedic technology.
Why is 18Ni alloy used in the study of lath martensite?4 answersThe 18Ni alloy is used in the study of lath martensite because it exhibits certain characteristics that make it suitable for investigation. In the as-quenched condition, the alloy shows the presence of dislocations with very high density, which can be observed through neutron diffraction experiments. Additionally, the alloy undergoes martensitic transformation, which is accompanied by the generation of internal stresses. These internal stresses have been studied using X-ray or neutron diffraction, but the results have been inconsistent due to various factors influencing the measured lattice parameter. Furthermore, the 18Ni alloy has been found to exhibit an increase in strength with carbon content, and the mechanism behind this strengthening is still not fully understood. Tensile tests on lath martensite samples without retained austenite have shown that the strength of the alloy increases with the refinement of effective grains, suggesting a relationship between carbon content, grain refinement, and strength enhancement.
How does the crystallite size of LaFeO3 compounds change with calcination temperature?3 answersThe crystallite size of LaFeO3 compounds changes with calcination temperature. In the hydrothermal synthesis of LaFeO3, the introduction of carbonate into the system decreases the formation temperature of LaFeO3 by about 150°C. For nanocrystalline powders of La1−xSrxMnO3, the crystallite size increases with increasing calcination temperature. In the case of silica-supported and unsupported iron oxide catalysts, the average crystallite sizes range from 25 to 95 nm for the supported samples and from 145 to 61 nm for the unsupported samples. The effect of calcination temperature on the crystallite size of MgO/TiO2 catalysts for the trans-esterification of soybean oil shows that the crystallite size decreases with the decrease in calcination temperature. In Mg2+-substituted LaCrO3 compounds, the grain sizes of La(Cr1-xMgx)O3 materials increase with increased Mg2+ content.
