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).
