Physical Metallurgy - Part 1 by Vijendra Singh presents fundamental structure-property concepts across metals, alloys, phase diagrams, crystal geometry, and defects. The content starts with bonding types, crystalline versus non-crystalline solids, space lattices, crystal structures, and lattice position notations using Miller indices. It then extends to alloy structure and solid solutions, followed by phase rule, unary/binary diagrams, and determination methods. Later sections develop defect classifications, dislocations, surface and grain-boundary defects, and set the basis for solidification and deformation topics.

FAQs

What bonding types are covered in the book’s structure of metals section?

The book introduces ionic, covalent, van der Waals, and metallic bonding, then links metallic properties to metal behavior.

How does the text treat crystal structures and their notation?

It explains crystalline versus non-crystalline solids, space lattices, common metal crystal structures (BCC, FCC, HCP), and uses lattice position and Miller index-based notations for planes and directions.

What topics are included in the phase diagrams chapter?

It covers the phase rule, unary and binary diagrams (including eutectic and peritectic systems), uses of phase diagrams, and methods for determining them such as thermal analysis and microscopic/X-ray approaches.
