Alloying Metals/Thermal Equilibrium Diagrams

Seite 1

What are Alloys/Why are metals alloyed.

Alloys are combinations or mixtures of elements.

Metals are alloyed to improve on properties of pure

metals such as hardness, strength, corrosion resistance, etc.

Alloys may behave

differently when combined, some mix easily while others will only be soluble to

a limited extent. Thermal Equilibrum diagrams seek to interpret how alloys combine.

Solid

Solution Alloys

Two metals are

completely soluble in each other. Solid solution alloys are normally:

•Substitutional solid solution or,

•Interstitial solid

solution.

Copper-nickel alloy

is a solid solution .
