Aging and overaging processes in Pb-0.08%Ca-x%Sn alloys using transmission electron microscopy and differential scanning calorimetry

Contribution of the associated complex in a binary liquid to model the Ca–Pb–Sn ternary system

“…5). This latter result confirms the experimental information provided by the literature [25]. Indeed, the tin content of the hardened precipitates Ca(Pb 1Àx Sn x ) 3 of L1 2 -type has increased during the overaging process as it is predicted by the tie-line evolution on the isothermal section drawn at 300 K (Fig.…”

Corrosion management of PbCaSn alloys in lead-acid batteries: Effect of composition, metallographic state and voltage conditions

“…This observation explains that the hardness value of overaged PbCaSn 2 wt.% remains high. As observed by several authors in the literature, the presence of high content of tin inhibits the overageing process of PbCa alloys [12,13].…”

“…The weight loss and the oxygen evolution of the overaged alloys are almost systematically higher than that of aged alloys. As shown by a previous study [13], the overageing process cause an increase of tin content in precipitates and a decrease of tin content in the lead matrix, so the bad corrosion resistance of the overaged alloys is closely related to a low tin content in lead matrix all along the overageing process. Another factor responsible for the high corrosion rate in overcharge conditions is the O 2 gas evolution.…”

The influence of tin and silver as microstructure modifiers on the corrosion rate of Pb–Ca alloys in sulfuric acid solutions

“…4 and 5. The additional constriction of the spaces between the grains during the quenching process, beneficially suppresses the intercrystalline corrosion [14,15,[18][19][20].…”
