This Material Science textbook by Asha L. Gawali, Prof. Rahul B. Barjibhe, and Sanjay Chhoturam Kumawat is specifically written for Semester III Mechanical Engineering students at Maharshi Dayanand University (MDU). It provides a comprehensive foundation for understanding the properties, structures, and applications of engineering materials in alignment with the university's revised syllabus.

🔬 Core Topics Covered

• Crystal Structures & Imperfections: Detailed study of unit cells, space lattices (like BCC and FCC), and various crystal defects that influence material strength.

• Phase Diagrams: Analysis of equilibrium diagrams, particularly the Iron-Carbon ($Fe-C$) diagram, to understand how different phases form during cooling.

  • Heat Treatment Processes: Exploration of techniques like annealing, normalizing, hardening, and tempering used to modify the mechanical properties of metals.

• Material Testing & Corrosion: Introduction to destructive and non-destructive testing methods, along with the causes and prevention of material degradation.
