The preparation of an aluminum-mesoporous A1-MCM-41 humidity control material (Al-MHCM) by hydrothermally synthesizing a mixture of thin-film transistor liquid crystal display (TFT-LCD) waste glass and sandblasting (SB) waste was studied. The product has a typical mesoporous structure, with a specific surface area of up to 1013 m2/g, the pore size distribution calculated is 3–4 nm, and the pore volume of 0.97 cm3/g. All the aluminum atoms of the product are in the form of tetrahedral aluminum in the framework, which confirms the successful synthesis of Al-MHCM. Results show that when the hydrothermal synthesis temperature is 105 °C, the product synthesized from a mixture with a Si/Al molar ratio of 41.8 exhibits excellent performance (91.45 m3/m3) in terms of the equilibrium moisture content and moisture adsorption capacity. The results confirm that the equilibrium moisture content of Al-MHCM is better than the rape straw concrete and hemp concrete (9.8–17.8 m3/m3), and that of a diatomite/ground calcium carbonate composite aterial (11.7 m3/m3). The research results are expected to provide a new technology for synthesizing TFT-LCD waste glass and SB waste into novel high value-added humidity control materials. Resumen: Se estudió la preparación de un material de control de humedad de aluminio-mesoporoso A1-MCM-41 (Al-MHCM) mediante la síntesis hidrotermal de una mezcla de vidrio de desecho de pantalla de cristal líquido de transistor de película delgada (TFT-LCD) y desechos de arenado (SB). El producto tiene una estructura mesoporosa típica, con una superficie específica de hasta 1013 m2/g, la distribución del tamaño de poro calculada es de 3-4 nm y el volumen de poro de 0,97 cm3/g. Todos los átomos de aluminio del producto están en forma de aluminio tetraédrico en la estructura, lo que confirma la síntesis exitosa de Al-MHCM. Los resultados muestran que cuando la temperatura de síntesis hidrotermal es de 105 °C, el producto sintetizado a partir de una mezcla con una relación molar Si/Al de 41,8 presenta un excelente rendimiento (91,45 m3/m3) en términos de contenido de humedad de equilibrio y capacidad de adsorción de humedad. Los resultados confirman que el contenido de humedad de equilibrio de Al-MHCM es mejor que el hormigón de paja de colza y el hormigón de cáñamo (9,8–17,8 m3/m3), y que el de un material compuesto de diatomita/carbonato de calcio molido (11,7 m3/m3). Se espera que los resultados de la investigación proporcionen una nueva tecnología para sintetizar residuos de vidrio TFT-LCD y residuos SB en nuevos materiales de control de humedad de alto valor añadido.

Interstitial free (IF) steels are popular in the automotive industry for applications requiring good ductility (formability), strength and a superior surface quality. Magnetic anisotropy measurement can be used to gain information about the crystallographic texture, which is an important property controlling strength and especially the formability, for example rvalues. The crystallographic texture is generated during rolling and subsequent recrystallisation during the annealing heat treatment. A set of IF steel specimens, at different states of recrystallisation (cold rolled, partially recrystallised and fully recrystallised) and accordingly different texture components have been used to investigate measurement and prediction of magnetic anisotropy. A finite element microstructure model that considers crystallographic texture based on magnetic domain theory has been used for the evaluation of magnetic anisotropy in polycrystalline steels. In addition, a laboratory based electromagnetic (EM) U shaped sensor has been proposed to determine the magnetic anisotropy in IF samples by measuring at angles varying from 0° to 90°, in steps of 15°, with respect to the rolling direction. Kernel Average Misorientation (KAM) values from Electron Back Scattered Diffraction (EBSD) characterisation of the samples has been used to evaluate the recrystallisation fraction and correlate that to the texture.
