Titanium Alloys illustrates how alloy microstructures are affected by various thermomechanical treatments present in real world operating conditions.

Features:

• Covers microstructures and fracture features of a-, a + ß-, ß-, and Ti3Al-based aluminides tested at various conditions and temperatures
• Features the largest photographic collection ever assembled in a single volume with nearly 400 photographs of fracture features resulting from deformation mechanisms occurring at different temperatures, stress states, and strain rates
• Includes a CD-Rom of the fracture feature images presented in the book
• Provides illustrations and information on non-American standard alloys, previously inaccessible to American aero engine manufacturers
