Abstract

La demanda es la puerta de entrada al proceso de litigio. Con ella se garantiza el acceso a la justicia y la posibilidad de tener voz activa en la reivindicación de los derechos que se juzgan vulnerados. Este artículo no pretende innovar, sino más bien reforzar los procedimientos procesales que regulan tan importante instrumento jurídico. Nos gustaría que este artículo sea de utilidad para los estudiantes de Derecho Canónico y que sirva también como material de repaso para todos los canonistas que trabajan en los Tribunales.

Abstract

The room temperature magnetostriction of polycrystalline Fe100– x Cr x alloys annealed at 800 °C was investigated as a function of Cr content varying from 10 to 30 at.% Cr. All alloys exhibited a single bcc $\alpha $ -Fe–Cr phase with a disordered A2 structure. With increasing Cr concentration, the grain shape became very elongated. The greatest total magnetostriction value of $70 \times 10^{-6}$ was obtained in the direction of the elongated grains for 30% of Cr. We also investigated the effect of B addition on the magnetostriction and structural properties of the alloy Fe80Cr20. Although the addition of B was expected to form the Fe2B phase, the B-added Fe–Cr alloy forms a ternary phase (Fe z Cr1– z )2B ( $0 ), a weak magnetic phase.
