Oxidation behavior of titanium aluminides
Le Journal de Physique IV, 1993 Results from an ongoing study of the high temperature oxidation of intermetallic compounds in the Ti-Al system are presented. The oxidation behavior of alloys based on TiAl (γ) has been found to be extremely complex depending on temperature and atmosphere composition.

Microstrain Analysis of Titanium Aluminides [PDF]
Materials Science Forum, 2010 The aeronautic and automotive industries have shown a renewed interest in TiAl based alloys. The main reasons for such an interest are their low density (~3,8g/cm3), a good stiffness and a high strength for temperatures up to 750°C. However, these alloys exhibit, in their polycrystalline form, a poor ductility at room temperature with widely scattered ...

Journal of Engineering, Volume 2025, Issue 1, 2025.The present work focuses on optimizing spatter size, taper angle, and circularity simultaneously during fiber laser trepan drilling of stainless steel thin sheet using Taguchi–grey relational analysis (GRA). The controllable process factors such as trepanning speed, average laser power, and pulse frequency with five levels are applied to conduct the ...

Engineering Reports, Volume 6, Issue 12, December 2024.The graphical abstract demonstrates that adding 9 wt% nickel to an Al‐Si matrix composite increases hardness by 25.93%, tensile strength by 40.3%, and density by 6.01%, but decreases impact strength by 50% compared to the A413 alloy. It includes SEM images, a stir casting schematic, and data on tensile and impact behavior.

Materials and Corrosion, Volume 75, Issue 12, Page 1583-1599, December 2024.Hot corrosion is encountered in turbine engines, where Co‐based superalloys are proposed to replace Ni‐based materials. In the present study, the hot corrosion resistance of γ/γ′ superalloys of the Co–Ni–Al–W alloys was increased by their Co and W content.

Knudsen effusion mass spectrometry: Current and future approaches
Rapid Communications in Mass Spectrometry, Volume 38, Issue 14, 30 July 2024.Rationale Knudsen effusion mass spectrometry (KEMS) has been a powerful tool in physical chemistry since 1954. There are many excellent reviews of the basic principles of KEMS in the literature. In this review, we focus on the current status and potential growth areas for this instrumental technique.
