Volume diffusion and grain boundary diffusion of carbon 14 in molybdenum

Creators

Description

Diffusion tests, using 14C as a tracer, were carried out on as-cast molybdenum sample containing 30 and 300 ppm of carbon. Various diffusion mechanisms are proposed: diffusion in the vacancies and the dislocations, intergranular diffusion. Micrography examinations show the location of carbon and its important effects on Mo microstructure, mechanical behavior and diffusion phenomena

Abstract (French)

On a effectue, en utilisant le C14 comme traceur, des essais de diffusion sur des echantillons de molybdene bruts de fusion, contenant 30 et 300 ppm de carbone. On propose divers mecanismes de diffusion: diffusion dans les lacunes et les dislocations, diffusion intergranulaire. Des observations micrographiques ont mis en evidence la localisation du carbone et son role important sur la microstructure du molybdene, le comportement mecanique et les phenomenes de diffusion
