2. Titanium Aluminides: Surface Composition Effects as a Function of Temperature. Figure 3 shows the surface variation of oxygen concentration as a function of temperature from 20 C to C for pure Ti, alpha-2 aluminide and gama aluminide. The alpha-2 and gama aluminides had the same initial oxygen concentration, but as compared with pure titanium. : Hydrogen Transport and Cracking in Metals: Proceedings of a Conference Held at the National Physical Laboratory, Teddington, UK, April (The Institute of Materials Book, No ) (): Turnbull, Alan: BooksCited by: 2.

Hydrogen Embrittlement in Titanium Alloys. Titanium Overview Titanium-based alloys provide an excellent combination of a high strength/ weight ratio and good corrosion behavior, which makes these alloys among the most important advanced materials for a variety of aerospace, marine, industrial, and commercial applications. This paper addresses the hydrogen embrittlement of titanium-based alloys. The hydrogen-titanium interaction is reviewed, including the solubility of hydrogen in α and β phases of titanium and hydride formation. Also, the paper summarizes the detrimental effects of hydrogen in different titanium alloys. Proceedings of the Fifth International Conference on the Effect of Hydrogen on the Behavior of Materials sponsored by the Structural Materials Division (SMD) Mechanical Metallurgy and Corrosion & Environmental Effects Committees of The Minerals, Metals & Materials Society held at Jackson Lake Lodge, Moran, Wyoming, September , Hydrogen trapping in titanium alloys. Hydrogen embrittlement is induced by a critical combination of sensitive material and hydrogen content absorbed within the material. Generally, the absorbed hydrogen is not homogeneously distributed inside the by: 4.

  Two-phase (Ti3Al and TiAl) TiAl and TiAl (at. pct) alloys, which were preoxidized in static air at K ( °C) for times between seconds ( hours) and ks (4 hours), were charged thermally at K ( °C) with flowing hydrogen gas at a pressure of MPa for 72 ks (20 hours), and the effect of oxide layers on hydrogen penetration (or Cited by: This is a concise introduction to titanium alloys and focuse s on the most relevant aspects for the book, namely the effect of the thermo mechanical processing of titanium alloys and aluminides. The chapter includes a section on the most common alloys, as the large number of alloys found in the literature can be very confusing. This is based on a combination of properties including light weight, good oxidation resistance with respect to conventional titanium alloys, and good high temperature mechanical properties. These materials are also becoming critical to the development of future hydrogen driven energy systems including hypersonic transport [4].Author: W. Wei, W. Dunfee, M. Gao, R. P. Wei.
