Aim of this note provides the students to an
understanding of mechanics, physical and chemical properties of materials
including metals, ceramics, polymers and composites and the reasons for these
properties to exist. Topics covered includes: Atomic Structure, Interatomic
Bonding and Structure of Crystalline, Imperfections in Solids, Mechanical
Properties of Metals, Diffusion, Dislocations and Strengthening Mechanisms,
pplications and Processing of Metals and Alloys, Phase Diagrams, Composites,
Corrosion and Degradation of Materials.
This textbook, authored by Dr. Swati
Gangwar and Mr. Kapil Kumar, comprehensively covers the very basics of
material science and engineering. Classifications of materials are taken up
as metals, polymers, composite materials, and biomaterials; their properties
and applications are described. Crystal structures are discussed in terms of
Bravais lattices, Miller indices, and atomic packing factor. Students will
also be introduced to X-ray crystallography and how it might be applied for
the determination of inner structure of the materials. Its clarity in
structure and rich detail make it extremely useful for courses ranging from
introductory to advanced in material science and engineering. Significant
emphasis throughout the text, quite markedly, on the importance of
understanding material properties and their relationship with structure
toward an effective design and application of an engineering material.
This lecture note deals with
the important areas that explain the interplay of materials, structure, and
properties as tackled by the engineers. Metallurgy to crystal physics and
Neumann's symmetry principle also have been dealt with. Equilibrium
thermodynamics, neutron diffraction, and spectroscopy discussed alongside
the major classes of materials and emerging nanostructured materials have
also been dealt in this note. Since the material emphasizes practical
applications, it is presented within the framework of advanced concepts like
Moore's law and its implications for materials engineering. The note will
prove useful to both engineering students and practicing engineers, and it
discusses the scientific method as applied to questions of material
selection and performance.
