Tin melts at about 450°F, while lead melts at about 620°F. When they come together as two components, the solder melts at 370°F. That is 80 degrees below where tin melts and 250 degrees below where lead melts.
WebNov 16, 2024 · In the phase transformation from S 1 to S 2, the reaction is endothermic (Δ H > 0) and the volume expands (Δ V > 0). This means the slope of the boundary line between S 1 and S 2 is positive. The slope of the other boundary line can also be estimated.
