What is the difference between eutectic and eutectoid points?

Answer 1

The eutectic point of a mixture is defined as the temperature at which a eutectic mixture freezes or melts. A eutectic mixture is a mixture that melts and solidifies at a single temperature that is lower than the melting points of the individual constituents.

Answer 2

there is no a remarkable difference between eutectic and eutectic, however differences can be there only if the eutectic minerals involved can reach their liquidus, at varying temperatures thus we can say that there is a difference between eutectic point of suppose mineral A and mineral B. thus we can say there is no any eutectic difference in the same mineral but in different mineral elements

Answer 3

Eutectic point is where a liquid eutectic composition cools sufficiently to solidify.

Eutectoid point is where, within a solid, the material cools enough to undergo a phase transformation. e.g. austenite to cementite and ferrite.

Answer 4

The eutectic point refers to a specific composition in a binary phase diagram where a liquid phase transforms into two distinct solid phases upon cooling. On the other hand, the eutectoid point is a specific composition in a phase diagram where a single solid phase transforms into two different solid phases upon heating.

Answer 5

It is the min. temp. above which liquid can exist.
