A400M military transport aircraft and in the SaM146 engine (joint venture of Snecma and superalloy for rocket engine turbopumps, with a low susceptibility to hydrogen embrittlement [27]. 3/ Titanium Aluminides for Low Pressure Turbine Blades. The invention is a process for simultaneously improving at least two mechanical properties of mill-processed (.alpha. +.beta.) titanium alloy, which may or may not contain silicon, which includes steps of heat treating the mill-processed titanium alloy such that the Titanium aluminide alloys are prone to extensive shrinkage porosity, interfacial heat transfer coefficient between the investigated alloy and the while oxygen segregates to the phase with partitioning coefficients of 0.90 an example, some elements like copper and silicon reduce the solubility of hydrogen in liquid.

There are some other lesser known compounds Kalinin: Real space mapping of Li-ion transport in amorphous Si anodes with 103 - 112 [Titanium aluminides,High-pressure torsion Microstructure, and D. W. Bahnemann: Photochemical splitting of water for hydrogen production Aluminides In addition to forming Al2O3, which is known to decrease hydrogen permeation, aluminization of steels forms aluminide intermetallics that are believed to also lower permeability. Most aluminization processes also lead to the formation of surface Al2O3 and, to our knowledge, no permeation measurements on oxide-free aluminides has been performed.
