Mt4 phase diagram of pb-sn alloys lab report

Webprimary Sn phase will readily nucleates Pb phase at under-coolings between 0 and 0.5 K, while it seems that primary Pb phase does not nucleates effectively the Sn phase, which produces an undercooling as large as 55 K for Sn phase nucleation. The results of the undercooling obtained in this work, shown in Table 1, indicates that it was observed WebThe alloy is a single-phase solid solution, on ‘Weight porcent tin igure 11-8 Solidification, precipitation, and microstructure of a Pb-10% Sn alloy.
