Diffusion and Kinetics:
a) State Fick’s first and second laws and explain when each is used. (6)
b) For diffusion-controlled growth, give the Arrhenius form of the diffusion coefficient and explain how temperature affects diffusion distance for a fixed time. Include a worked example: if D = D0 exp(−Q/RT) with D0 = 1×10−4 m2/s, Q = 200 kJ/mol, compute D at 800 K (R = 8.314 J/mol·K) and estimate root-mean-square diffusion distance after 1 hour.

Professor V. Raghavan is a stalwart in the field of materials science. Formerly a professor at the Indian Institute of Technology (IIT) Delhi, his expertise lies in phase diagrams, crystallography, and physical metallurgy. His writing style is famously concise, exam-oriented, and technically precise. Unlike many Western textbooks that can be verbose, Raghavan’s work is tailored specifically for the Indian subcontinent’s curriculum, where clarity and problem-solving take precedence over lengthy prose. Q = 200 kJ/mol
Phase Diagrams & Transformations: Detailed analysis of thermodynamic functions, equilibrium, and the Iron-Carbon system.

In the world of engineering curricula, few subjects are as foundational—and often challenging—as Materials Science. For decades, students and educators in India and abroad have relied on a standard text to demystify this subject: "Materials Science and Engineering: A First Course" by V. Raghavan.
