Hf6Al7 and Hf4.44(1)Nb1.56(1)Al7—the First Fully Ordered Main Group Metal Containing W6Fe7 Type Compound and its Ternary Coloring Variant

Zeitschrift für anorganische und allgemeine Chemie, Volume 651, Issue 11, July 22, 2025.
Hf4Nb2Al7 and Hf6Al7 were synthesized from the elements and crystallize in the rhombohedral W6Fe7 type structure. Single crystals showed obverse‐reverse twinning. In addition, 27Al NMR investigations, magnetic measurements and quantum‐chemical calculations were conducted. Attempts to synthesize Hf4NbAl7 led to the discovery of nominal Hf4Nb2Al7 instead

Corrosion Behavior of a Thermally Oxidized Orto-Titanium Aluminide in Synthetic Seawater

International Journal of Electrochemical Science, 2015
Corrosion behavior of the Ti-22Al-25Nb alloy, thermally oxidized at 850 °C for 1 h, 10 h and 20 h, respectively was studied in synthetic seawater. SEM, XRD and Raman analysis confirm the presence of mostly of the rutile niobian compound, Ti0.952Nb0.048O2

Improving Cyclic Oxidation Resistance of Additively Manufactured IN939 Superalloy via Chemical Vapor Aluminizing

Advanced Engineering Materials, Volume 27, Issue 7, April 2025.
This study investigates the effect of a NiAl coating on additively manufactured (AM) IN939 to improve its cyclic oxidation resistance at 1050 °C. The coating promotes protective α‐Al2O3 formation, allowing durability for up to 240 cycles, while uncoated AM‐IN939 experiences spallation and weight loss due to nonprotective oxides.
