Aeutectic alloy is which of the following (two correct answers): (a) the composition in an alloy system at which the two elements are present in equal proportions, (b) the composition in an alloy system for which the solidus and liquidus are at different temperatures, (c) the composition in an alloy system for which the solidus and liquidus are at the same temperature, (d) the composition in an alloy system that has the highest melting point, and (e) the composition in an alloy system that has the lowest melting point?

Option (c) and option (d)

Explanation:

Eutectic system is one in which a solid and homogeneous mixture of two or more substances resulting in the formation of super lattice is formed which can melt or solidify at a temperature lower than the melting point of any individual metal.

Eutectic alloys are those which have its components mixed in a specific ratio.

It is the composition in an alloy system for which both the  liquidus and solidus temperatures are equal.

Eutectic alloys have the composition in which the melting point of the metal is lower than the other alloy composition.
