Dynamic Fracture Properties of Titanium Alloys

Fatigue precracked specimens of three titanium alloys (6Al-4V, ELI, and Timetal 5111) were dynamically loaded in a drop weight tower system while the dynamic fracture toughness was inferred using Coherent Gradient Sensing, crack opening displacement, or strain gage methods. A comparison of the initiation toughness of the three materials as a function of loading rate and specimen thickness is made.

Titanium Alloys

Although originally discovered in the 18th century [1], the titanium industry did not experience any significant advancement until the middle of the 20th century through the development of the gas turbine engine [2]. Since then, the aerospace sector has dominated worldwide titanium use with applications in both engines and airframe structures [3]. The highly desirable combination of properties,...

Properties and Applications of Titanium Alloys: a Brief Review

This paper presents a brief review on titanium alloys, giving especial attention to Ti6Al-4V. The mechanical and the thermal properties were highlighted, while with regard to application the emphasis was placed to the aerospace, automotive and biomedical fields. The tensile strength of the alloys under concern varies from about 200 to 1400 MPa, but for Ti-6Al-4V the range is from about 900 to 1...

Nanomechanical properties of surface-modified titanium alloys for biomedical applications.

The mechanical properties of the oxide layers developed at elevated temperature on three vanadium-free titanium alloys of interest for biomedical applications were investigated by means of the nanoindentation technique. The as-received alloys (Ti-13Nb-13Zr, Ti-15Zr-4Nb and Ti-7Nb-6Al) and their oxide scales formed by reaction with air at 750 degrees C for several oxidation times were analysed c...
