Chapter 14, Problem 14.18P

Interpretation Introduction

Interpretation:

The copper containing 40% Zn or 9% Al needs to be proved in a single phase

Concept introduction:

Copper material remains a single phase even after containing 40%Zn or 9%Al. In metallurgy, the term phase is used to describe the physical homogeneous state of matter where it derives chemical composition, atomic bonding, and arrangement of elements. If there is more than one phase than each phase in alloy or material has its own different physical, chemical, electrical and mechanical properties. The phase thus represents the alloy composition.
