The phase diagram ... eutectic invariant reaction between these two constituents. At the eutectic temperature of 183 C, three phases exist in equilibrium: (Pb) with the composition Pb-19 wt % Sn, (Sn) ...

Phase analysis confirmed that minute levels of Mn substituted for Ni in the system drastically shifts the liquidus projection in the Al-rich corner of the ternary phase diagram such that the eutectic ...
