**Chapter 7 111**

Experimentation and Optimization of Multilayered Aluminum-Based Functionally Graded Materials *by Pattapagalu Naga Sudhakar Srinivas, Pittam Srinivas Rao, Kolari Deepak and Nallamilli Srinivas Reddy*

Preface

*New Advances in Powder Technology* consists of seven chapters that discuss powder

Section 1, "Fabrication of Powders", includes two chapters. Chapter 1 focuses on the spray pyrolysis synthesis of powders and their applications as electrode materials. Chapter 2 discusses the additive manufacturing of powders by direct laser deposition method. It also presents the main requirements for the direct laser deposition method and characterizes the prepared metal powders. This section is useful for powder

Section 2, "Wettability of Powders", includes three chapters. Chapters 3–5 focus on the wettability properties of powders by measuring the interface of the powders and the dispersing media by the sessile drop method and the capillary rise technique.

Section 3, "Consolidation of Powders", includes Chapters 6 and 7, which discuss the consolidation of metal powders by spark plasma sintering and conventional sintering methods, respectively. Both chapters investigate the density and mechanical and surface properties of metal and alloy powders. They also report on the microstructure evolution of powders during consolidation. Section 3 is useful for metallurgists, powder metallurgists, material researchers, and mechanical engineers to understand

Overall, this book is an informative resource for a wide range of readers, including
