Aspectos experimentales de la determinacion de curvas esfuerzo-deformacion a alta temperatura y en atmosfera controlada: Refractarios Al<sub>2</sub>O<sub>3</sub>-MgO-C

Abstract: Se presenta una metodología diseñada e implementada en el Laboratorio de Materiales Estructurales de la División Cerámicos del INTEMA para la evaluación del comportamiento mecánico de materiales refractarios a altas temperaturas y en atmósfera controlada. La metodología comprende la determinación de la deformación por extensometría de contacto en ensayos en compresión con el fin de obtener curvas esfuerzo-deformación y el uso de un sistema de control de atmósfera por desplazamiento a través del pasaje de una c… Show more

“…The response to thermal and mechanical loadings of AMC bricks was studied by the measurement of stress-strain curves in compression, at room temperature (RT), 700, 1000 and 1260 1C, in a non-oxidant atmosphere (nitrogen), using an experimental protocol specially designed for oxide-C refractories [21,23].…”

“…In these cases, the presence of graphite allows the brick to adjust the effort applied through the creep, thus increasing the strain at the fracture [13].…”
