Preface

Metallurgical engineering and electrodeposition of metals and alloys are of great importance in several fields such as physical metallurgy, extractive metallurgy, mineral processing electroplating, electrowinning, and electrorefining. This book shares recent research and knowledge related to metallurgical engineering and electrodeposition, and contains 10 chapters. Chapter 1 briefly explains the introduction of engineering materials and metallurgy. Chapter 2 introduces the importance of understanding the role of substitutional nickel in the structure, microstructure, and selected mechanical properties of titanium–nickel (Ti–Ni) system alloys. Chapter 3 shows the effect of alloying elements such as Ti, Mn, Be, Zr, and B on the phase transitions and enhancement of the mechanical properties of Cu-based shape memory alloys. Chapter 4 discusses the fabrication of dielectric thick film by electrophoretic deposition and its characterization. Chapter 5 illustrates the general principles and electrolyte optimization of cooperative interaction mechanisms between metastable-state ions and electrolytes.

Chapter 6 explains the metal organic framework of ionic liquids. Chapter 7 presents the characterization and treatment of real wastewater from an electroplating company using raw chitin. Chapter 8 deals with the mechanical properties analysis of austempered ductile iron weld joints using a developed electrode. Chapter 9 exposes the influence of spark plasma sintering parameters on the mechanical properties of high-entropy alloys for aerospace applications. Chapter 10 explains the cutting of super-hard materials using jet methods. The purpose of this chapter is to develop the principles of a functional approach to create hybrid processes in a morphological combination of energy flows impacted on a workpiece.

We hope that the knowledge and objectives of recent research achievements in metallurgical engineering and electrodeposition will be useful for researchers, students, engineers, and others that work with these kinds of materials.

I acknowledge IntechOpen for their enthusiastic and professional support. I would like also to express my thanks to the editor panel, Dr. Dhanasekaran Vikraman and Dr. K. Karuppasamy, for their endless scientific support, and to the authors who contributed their findings related to metallurgical engineering and electrodeposition. Without their expertise and contributions, this book would not have been possible.
