Chapter 10, Problem 10.65P

Interpretation Introduction

Interpretation:

The effect of heating the given composite of $500\text{ g}$ Cu and Ni to ${1150}^{\circ }\text{C}$ and being held there for several years is to be explained.

Concept Introduction:

On the temperature-composition graph of an alloy, the curve above which the alloy exist in the liquid phase is the liquidus curve. The temperature at this curve is maximum known as liquidus temperature at which the crystals in the alloy can coexist with its melt in the thermodynamic equilibrium.

Solidus curve is the locus of the temperature on the temperature composition graph of an alloy, beyond which the alloy is completely in solid phase. The temperature at this curve is minimum and is known as solidus temperature at which the crystals in the alloy can coexist with its melt in the thermodynamic equilibrium.

Percentage of a component in an alloy is calculated as:

  $\%x_i=\frac{m_i}{{\displaystyle \sum _i{m}_i}}\times 100\%$   ...... (1)
