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 ...

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.

Aluminium evaporation during ceramic crucible induction melting of titanium aluminides [PDF]
, 2013 Melting TiAl based alloys in ceramic crucibles often leads to chemical contamination, alloy heterogeneity and non-metallic inclusions. The severity of such phenomena usually depends on the nature of crucible materials, the melting stock composition and ...

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.

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.

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.
