Solution
The properties of materials mainly depends on the internal arrangement of the atoms on
molecules.In the selection of materials, the awarenessregarding differences and similarities
between materials is extremely important. Metals of a single type atom are named pure metals.
Metals in actual commercial use are almost
exclusively alloys, and not pure metals, since it is possible for the designer to realize an infinite
variety of
physical properties in the product by varying the metallic composition of the alloy. Alloys are
prepared
from mixed types of atoms. Alloys are classified as binary alloys, composed of two components,
as ternary
alloys, composed of three components or as multi component alloys. Most commercial alloys
are multicomponent. The composition of an alloy is described by giving the percentage (either
by weight or by atoms)
of each element in it.
The basic atomic arrangement or pattern is not apparent in the final component, e.g. a shaft or a
pulley
but the properties of the individual crystals within the metallic component, which are controlled
by the
atomic arrangement, are mainly responsible for their application in industry.
One can determine the strength of a piece of metal by its ability to withstand external loading.
The
structure of metal or alloy responds internally to the applied load by trying to counteract the
magnitude of
the applied load and thus tries to keep the constituent atoms in their ordered positions if however
the load
is higher than the force which holds the atoms in place, the metallic bond becomes ineffective
and atoms
in the metal are then forced into new displaced positions. The movement of atoms from their
original
positions in the metal is termed as slip. The ease with which atoms move or slip in a metal is an
