Corrosion and microstructural analysis data for AISI 316L and AISI 347H stainless steels after exposure to a supercritical water environment
This article presents corrosion data and microstructural analysis data of austenitic stainless steels AISI 316L and AISI 347H exposed to supercritical water (25 MPa, 550 °C) with 2000 ppb of dissolved oxygen. The corrosion tests lasted a total of 1200 h but were interrupted at 600 h to allow measurements to be made. The microstructural data have been collected in the grain interior and at grain boundaries of the bulk of the materials and at the superficial oxide layer developed during the corrosion exposure.
SÍNTESE E ESTRUTURA DO COMPOSITO METAL-CERÂMICO 316L/SYCRO
The composite formed by 316L steel with 10% of Sr 1.8 Y 0.2 CrReO 6 (SYCRO) double perovskite was successfully sintered using Top Down nanotechnology associated with powder metallurgy. MEV images showed that the SYCRO nanoparticles were deposited on the steel surface homogeneously. The scattering spectra of the images confirmed the presence of the Sr and Re elements scattered homogeneously on the surface of the composite, which corroborates the images observed by SEM. X-ray diffraction measurements showed that SYCRO particles were embedded in the 316L steel matrix. Magnetic susceptibility a.c. showed that the composite has ferromagnetism and Tc close to that found in the literature for the ceramic composite Sr 1.8 Y 0.2 CrReO 6 , which certifies that the sintering of the composite was obtained successfully.
Fire Safety of Glued-Laminated Timber Beams in Bending
AbstractDesign models for timber structures with fire-resistance requirements usually take into account the loss in cross section due to charring and the temperature-dependent reduction in strength...
