Nanocrystalline Titanium

Grain refinement in metallic materials enables the effective enhancement of their strength and the achievement of unique chemical and physical properties. The majority of techniques for grain refinement in metals are severe plastic deformation (SPD) methods like high pressure torsion (HPT) and equal-channel angular pressing (ECAP). Enhanced strengthening effect is especially advisable for metals which in a solution strengthened state lose their valuable properties.

Nanocrystalline Titanium has been written with the main goal of discussing the general features of nanocrystalline titanium production by various SPD methods and to compare their microstructure and properties. The intention of the book's authors is also to characterize the physical, chemical and mechanical properties of ultrafine grained titanium and to indicate which are crucial for their application. Titanium alloys are characterized by high specific strength combined with excellent corrosion resistance.

Mechanical properties of pure (or commercial purity - CP) titanium are much lower. SPD methods are providing to be an effective way for increasing its strength even up to level typical for structural titanium alloys. This book will prove useful for academics and professionals studying the behaviour of metallic materials.
