Theory of Dislocations
This is the "Bible" for research in dislocations. It may be somewhat difficult to read if you do not have background in dislocations.
Introduction to Dislocations
This book provides a good entry-level introduction to dislocations. It is recommended as a first read if you do not have previous background in dislocations.
Elementary Dislocation Theory
Another reasonable introductory text to dislocations. Chris and Keonwook both started learning dislocation theory from this book.
This book provides the basic materials science background in ceramics. It is important if your research is in solid oxide fuel cells.
Fatigue of Materials
A must read if your research is related to metal fatigue.
Covers all aspects of mechanical deformation of metals --- e.g. continuum plasticity, dislocations, cracks, fatigue, creep, mechanical tests, metal forming. Comprehensive and easy to read.
Crystal Growth For Beginners
Very good book --- though you need to have a good background in thermodynamics and statistical mechanics. The book has 546 pages in total.
Computer Simulation of Liquids
This is the classic text on molecular simulations. But since it is about 20 years old, several important methods are not discussed in this book.
Understanding Molecular Simulation: From Algorithms to Applications
This book provides an update to Allen and Tildesley's book with discussions on more advanced algorithms. It is a good reference but may be too advanced if you did not have any background in molecular simulations.
This book explains the ideas behind the algorithms very clearly.
Statistical Mechanics: Entropy, Order Parameters and Complexity
Introduction to Modern Statistical Mechanics
Somewhat advanced, but very interesting to read. This is the book that Spider man uses when studying nanotechnology.
Introduction to the Theory of Metastable and Unstable States
An advanced and comprehensive review of nucleation theories.
Density-functional theory of atoms and molecules
Includes an introducion of density matrices and second quantization.
