Chapter 12, Problem 12.91AP

(a)

Interpretation Introduction

Interpretation: The structure that $\text{Ti}$ metal have at $1500\text{K}$ and $\text{6}\text{GPa}$ of pressure is to be identified and number of phase changes $\text{Ti}$ metal undergo as pressure is increased at $\text{725}{}^{\text{o}}\text{C}$ is to be stated.

Concept introduction: Phase diagrams are the equilibrium diagrams that show the phases and how these phases are affecting due to the changes in temperature, pressure and composition of an alloy.

There are three different lattices or structures, body-centered cubic (bcc), face-centered cubic (fcc) and hexagonal close-packed (hcp).

To determine: The structure that $\text{Ti}$ metal have at $1500\text{K}$ and $\text{6}\text{GPa}$ of pressure.

(b)

Interpretation Introduction

To determine: The number of phase changes $\text{Ti}$ metal undergo as pressure is increased at $\text{725}{}^{\text{o}}\text{C}$.
