Characterisation of lead – calcium alloys ageing in anisothermal conditions by calorimetric, resistance and hardness in-situ measurements
-
F. Rossi
Abstract
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 possible to identify five transformations. Complementary measurements have enabled us to define transformations with an in-situ electrical resistance measurement to follow the evolution of the calcium in solid solution and with an in-situ hardness measurement to characterise the mechanical properties. The aim of these results is to simulate the ageing and overageing of the alloy in isothermal conditions.
