Question

How would the electrical resistivity of metallic materials vary with composition for a simple eutectic system? [Hint: Sketch a diagram of simple eutectic phase diagram, and show below it the expected variation of the electrical resistivity].

Answer 1

Eutectic system:

It is a method of preparing alloys. Where two different melting temprature and electrical resistivity metals are heated so that it will converted to liquid or solid solution. Example copper and nickel. Then molten metal is allowed to cool so we can get changed composition of metal. for pure copper electrical resistivity is less and Nickel is greater then copper. byproduct of eutectic system having resistivity is greater then copper and lesser then nickel.
