Question

Any one good enough to explain Phase diagrams and Eutectic mixtures?

Answer 1

A eutectic mixture is a ratio of two materials such that the resulting mixture has the lowest possible melting point.

For the old lead based solder that mixture was 63% tin and 37% lead which melts at 180 C

Answer 2

you are similar to most people who have problems working with phase diagrams.  I have posted a link to a course of study that should help you

good luck and keep moving forward.....
