..., alloys containing between 36 and 87 wt% Pb separate into two liquids on further cooling. The two liquids coexist in the miscibility gap, or dome, that is typical of all alloys that undergo a monotectic reaction. During solidification of a copper-lead alloy containing 20 wt% Pb, the copper-rich α phase...

... of a liquid and a solid phase, Ω L and Ω S , lens-shaped isomorphous ( Fig. 2 ), eutectic ( Fig. 2 ), or pertitectic ( Fig. 2 ) phase diagrams can be obtained. A positive value of Ω φ results in the formation of a miscibility gap (a region of phase separation) at lower temperature. However, since...
