Nanocrystalline Titanium discusses the features of nanocrystalline titanium production by various SPD methods, also comparing their microstructure and properties. The authors characterize the physical, chemical and mechanical properties of ultrafine grained titanium, indicating which are crucial for their application. Titanium alloys are characterized by high specific strength combined with excellent corrosion resistance, whereas the mechanical properties of pure (or commercial purity - CP) titanium are much lower. SPD methods are proving to be an effective way to increase strength, even to a level typical for structural titanium alloys. This book is useful for academics and professionals studying the behavior of metallic materials.
