3. MATERIAL SCIENCE
Material science is the investigation of the
relationship among processing, structure,
properties, and performance of materials.

4. STRUCTURE1. Subatomic level - Electronic structure of
individual atoms that defines, interaction
among atoms (interatomic bonding).
2. Atomic level - Arrangement of atoms in
materials (for the same atoms can have
different properties.
3. Microscopic structure - Arrangement of small
grains of material that can be identified by
microscopy.
4. Macroscopic structure - Structural elements
that may be viewed with the naked eye.

5. PROPERTIES
Properties are the way the material responds to the
environment and external forces.
1. Mechanical properties – response to mechanical
forces, strength, etc.
2. Electrical and magnetic properties – response to
electrical and magnetic fields, conductivity, etc.
3. Thermal properties are related to transmission of heat
and heat capacity.
4. Optical properties include to absorption, transmission
and scattering of light.
5. Chemical stability in contact with the environment -
corrosion resistance. 5

6. SYNTHESIS AND PROCESSINGIt involves the creation of a material with the
desired micro/nanostructure.
From an engineering standpoint, a material
cannot be used in industry if no economical
manufacturing method for it has been
developed.
Thus, the processing of materials is very
important to the field of materials science.

7. MODERN MATERIAL NEEDS
• Engine efficiency increases at high temperatures: requires
high temperature structural materials.
• Use of nuclear energy requires solving problem with
residues, or advances in nuclear waste processing.
• Hypersonic flight requires materials that are light, strong
and resist high temperatures.
• Optical communications require optical fibers that absorb
light negligibly.
• Civil construction – materials for unbreakable windows.
• Structures: materials that are strong like metals and resist
corrosion like plastics.

8. RELATIONSHIP BETWEEN SCIENCE
AND TECHNOLOGY
Interdisciplinar study that combines metallurgy
physics, chemistry, and engineering to solve
real world problems with real world materials
in an acceptable social and economical
manner.
Science proposes explanations for
observations about the natural world.
Technology proposes solutions for problems of
human adaptation to the environment.
