Likewise, by joining the points B , B 1 , B 2 , B 3 , and B 4 , the solidus line, the temperature at which any given alloy will become completely solid, is obtained. In other...

..., because it is impractical to draw such a diagram on a flat page, the temperatures of simple surfaces are plotted as a series of contours on the triangle base in the same way that elevations are shown on a land map. As an example, the liquidus surface of this imaginary ternary eutectic is shown in Fig...

This is important because the brazing operation is carried out at temperatures just above the liquidus of the filler...
