Question

What are Alloys? Define with an example.

Answer 1

Answer:

The meaning of the term ‘alloy’ is a substance formed from the combination of two or more metals. Alloys can also be formed from combinations of metals and other elements. The properties exhibited by alloys are often quite different from the properties of its individual components. It is not uncommon for alloys to have greater strength and hardness when compared to pure metals. An example of an alloy is red gold, which is produced by alloying copper and gold together. Another important alloy of gold is white gold, which is produced by alloying silver and gold together.

Alloys can either be solid solutions of metallic elements in which all the individual grains/crystals of the metals are of the same composition, or they can be mixtures of metallic phases featuring at least two different solutions, resulting in microstructures containing different types of crystals inside the alloy. The term ‘intermetallic compound’ is used to refer to alloys that have well-defined crystal structures and stoichiometry. Furthermore, Zintl phases (products of chemical reactions between alkali metals or alkaline earth metals with post-transition metals or metalloids) can also be classified as alloys in some cases.

Alloys are known to feature metallic bonding. For almost all practical applications, the constituents of an alloy are measured in terms of their mass percentage. However, for some scientific studies, the components of alloys are measured in terms of their atomic fractions. It is important to note that alloys can be classified into two categories based on the arrangements of atoms in their respective lattices: substitutional alloys and interstitial alloys. It can also be noted that alloys can be classified based on the total number of phases present. For example, homogeneous alloys feature only one phase and heterogeneous alloys feature two or more phases....

Answer 2

Answer:

HEY MATE! HERE YOUR ANSWER

•Alloys are mixtures of two or more metals and a non-metal and cannot be separated into their components by Physical methods.

EXAMPLE:-

•Brass is a mixture of approximately 30% zinc and 70% copper.
