Ageing and overageing of lead-calcium alloys

Autor: A. Maitre, M. Lambertin, F. Rossi, Michel Vilasi, L. Delfaut-Durut

Publikováno v: Journal of Microscopy. 236:219-235

Summary Lead–calcium alloys are commonly used for their high mechanical properties, compared with pure lead. These alloys evolve quickly at room temperature and could in a few months, or years, undergo a softening (overageing). During the last deca

Transformations undergone by lead – calcium alloys are numerous and have different kinetics from a few minutes to a few years. Anisothermal calorimetric measurements were performed to be able to identify these transformations quickly. It was then p

International audience; Cast lead–calcium alloys were known to be sensitive to experimental parameters, which cause large variations on the ageing and overageing behaviour. From the study of these parameters, the quenching rate was the only signifi

International audience; The Pb–Ca is an age hardening alloy that allows for an increase in the hardness compared to pure lead. The hardening is obtained after different successive ageing transformations. In addition, this hardening is followed by a
