Preface

Titanium alloys, due to unique physical and chemical properties (mainly high relative strength combined with very good corrosion resistance), are considered as an important structural metallic material used in hi-tech industries (e.g. aerospace, space technology). Their development has led to the design of several groups of structural alloys, including single-phase α or β alloys, two-phase α+β alloys, and TiAl intermetallic alloys. Undoubtedly the consumption of titanium alloys has been continuously increasing in recent years. Although titanium and its alloys have been extensively researched for over 50 years, their application potential is still high. This has been confirmed by numerous recent publications and books presenting new findings on novel application areas for titanium alloys. This book aims to provide information on new processing methods of single- and two-phase titanium alloys.

The eight chapters of this book are distributed over four sections. The first section (*Introduction*) indicates the main factors determining application areas of titanium and its alloys. In the introductory chapter, the recent trends in design of titanium alloys and advanced technologies used for their processing are described briefly. The second section (*Manufacturing*, two chapters) concerns modern production

The next section (*Thermomechanical and surface treatment*, three chapters) covers problems of thermomechanical processing and surface treatment used for singleand two-phase titanium alloys. The fourth section (*Machining*, two chapters) describes recent results of high-speed machining of Ti-6Al-4V alloy and the pos-

The first chapter is the introduction. The second chapter reviews the modern production methods for titanium alloys. It presents the current methods used for modern applications. The author also discuss the future development related to the

The third chapter is devoted to two manufacturing processes intended for commercially pure titanium: laser and mechanical forming. The chapter discusses the most important aspects related to microstructure and mechanical properties of the

In the fourth chapter, bulk processing, including vacuum melting and hot working operations, is discussed. The sub-solvus forging is demonstrated as a method resulting in a superior combination of mechanical properties of beta titanium alloys. The chapter attempts to review the studies on manufacturing, plastic working, heat treatment, and surface modification of beta titanium alloys intended for aerospace

The fifth chapter describes the plastic flow behaviour of pseudo-alpha titanium alloy deformed at various temperatures and strain rates. The chapter presents processing maps elaborated on the basis of energy dissipation. The possibility of
