Tīmeklis2024. gada 26. febr. · Fe is a low-cost and strong β-stabilizing element in Ti alloys, and its addition improves the tensile strength of Ti alloys [ 8 ]. According to previous reports [ 20, 21 ], a 3 at.% addition of Fe will generate intermetallic compounds and reduce the plasticity of alloys. Therefore, the Fe content should not be excessive. Tīmeklis2024. gada 23. febr. · Fe–Zr–Ce–K samples were prepared by incipient wetness impregnation of K 2 CO 3 aqueous solution with a Fe/K molar ratio of 10:1 followed by drying at 120 °C overnight. Characterization Phases of the samples were analyzed on a Rigaku D/MAX 2200PC X-ray diffractmeter with Cu K α radiation (40 kV, 30 mA).

Tīmeklis2024. gada 1. okt. · With these criteria, Zr and Fe were shortlisted as they combine both low vapour pressure and low diffusivity in solid Al. Zr plays a dual role with the formation of primary Al 3 Zr resulting in grain refinement, limiting hot cracking, and its contribution to precipitation strengthening through post-ageing treatment [18].It diffuses in Al … TīmeklisThe Fe−Zr (Iron-Zirconium) system SpringerLink Alloy Phase Diagram Evaluations Published: October 1988 The Fe−Zr (Iron-Zirconium) system D.

Tīmeklis2024. gada 18. okt. · The temperature dependence of O/Zr atomic ratio in vapor over zirconia was analyzed: it turned out that evaporation occurs in a noncongruent mode at temperatures above 3000 K. Evaporation of the Zr–Fe–O system was greatly affected by the fast evaporation of FeO, implying that the atomic Zr/Fe ratio, less than 0.1 … TīmeklisIn this study, MoS2induced bimetallic–organic framework UiO-66(Fe/Zr) nanoparticles were prepared by a solvothermal method. Compared with that of pure UiO-66(Fe/Zr), MoS2/UiO-66(Fe/Zr) exhibits a higher peroxidase-like activity due to the generation of superoxide free radical (˙O2−).
