Chapter 11, Problem 11.18P

Interpretation Introduction

(a)

Interpretation:

The composition of the first solid which is formed during solidification needs to be determined.

Concept Introduction:

Freezing is the other name for solidification.

Solidification is the phase change of matter which results in the production of a solid phase from a liquid or molten phase.

Mostly, this phase occurs when the temperature of a liquid is lowered under the freezing point.

At the solidification temperature, atoms which are present in the liquid begins to bond and start the formation of crystals.

Interpretation Introduction

(b)

Interpretation:

The liquidus, solidus, solves and freezing temperature ranges of the alloy needs to be determined.

Concept Introduction:

Freezing is the other name for solidification. Solidification is the phase change of matter which results in the production of a solid phase. Mostly, this phase occurs when the temperature of a liquid is lowered under the freezing point. At the solidification temperature, atoms which are present in the liquid begins to bond and start the formation of crystals.

Interpretation Introduction

(c)

Interpretation:

The composition and amount at 260°C of each phase needs to be determined.

Concept Introduction:

Freezing is the other name for solidification. Solidification is the phase change of matter which results in the production of a solid phase. Mostly, this phase occurs when the temperature of a liquid is lowered under the freezing point. At the solidification temperature, atoms which are present in the liquid begins to bond and start the formation of crystals.

Interpretation Introduction

(d)

Interpretation:

The composition and amount at 183°C of each phase needs to be determined.

Concept Introduction:

Freezing is the other name for solidification. Solidification is the phase change of matter which results in the production of a solid phase. Mostly, this phase occurs when the temperature of a liquid is lowered under the freezing point. At the solidification temperature, atoms which are present in the liquid begins to bond and start the formation of crystals.

Interpretation Introduction

(e)

Interpretation:

The composition and amount at 25°C of each phase needs to be determined.

Concept Introduction:

Freezing is the other name for solidification. Solidification is the phase change of matter which results in the production of a solid phase. Mostly, this phase occurs when the temperature of a liquid is lowered under the freezing point. At the solidification temperature, atoms which are present in the liquid begins to bond and start the formation of crystals.
