On the Recrystallization of Alumimium Alloys Containing Titanium (Report 1)

Recrystallization Behavior of Commercial Purity Aluminium Alloys

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,...

Discoloration and Dissolution of Titanium Peroxide - or Fluoride - containing Solutionsand Titanium Alloys withImmersion in

fluoride-containing solutien. Commercially pure titanium (CP-Ti) and six titanium-based alloys were used: Ti-O.15Pd, Ti6Al-4V, Ti-7Nb-6Al, Ti-55Ni, Ti-10Cu, and Ti-20Cr. Two test solutions were prepared fbr immersion of polished titanium and titanium alloys: one consisting of O,2% NaF + O,9% NaCl (pH 3.8 with lactic acid) and the other of O.1 mol/1 H202 + O.9% NaCl (pH 5.5). Following immersion...

Corrosion behavior of pure titanium and titanium alloys in fluoride-containing solutions.

The effects of fluoride concentrations and pH on the corrosion behavior of pure titanium, Ti-6Al-4V, Ti-6Al-7Nb alloys and a new Ti alloy adding palladium, which is expected to promote a repassivation of Ti were examined by anodic polarization and corrosion potential measurements. The amount of dissolved Ti was analyzed by inductively coupled plasma mass spectroscopy. The surface of the specime...
