Chapter 11, Problem 11.19P

Interpretation Introduction

(a)

Interpretation:

The composition of the first solid formed needs to be determined.

Concept Introduction:

Solidification process is also known as a Freezing process which is a phase change of matter. This results in the solid phase formation. Regularly, this takes place at lower liquid temperature that is below the freezing point. Undercooling of liquids takes place in the process of solidification. Solidification can yield metastable product structures at high undercooling. The constituents of the metastable products are the result of kinetic competition.

Interpretation Introduction

(b)

Interpretation:

The liquidus, solidus, solvus and freezing temperature range of the Al-12% Mg alloy needs to be determined.

Interpretation:

The composition and amount of the phase at 525°C needs to be determined
