Elevated Temperature Oxidation and Corrosion of a Titanium Aluminide Alloy [PDF]

, 1997
Titanium aluminides are being developed to expand the temperature capability of titanium alloys with maximum service temperatures around 700*C. These materials also have the ability to replace nickel superalloys with potential applications in the high ...

Laser Metal Deposited Ti4822 Hollow Pipe: Experimental and Computational Modelling Study

Advanced Engineering Materials, Volume 28, Issue 3, 4 February 2026.
Laser metal deposition (LMD) of a crack‐free built Ti4822 alloys is challenging. This article reports outstanding characteristics of a hollow pipe that is built with LMD technology when a predicted, nontransformation substrate temperature of 800 °C is used.

Laser Melted TiC Reinforced Nickel Aluminide Matrix in situ Composites

, 2005
Titanium carbide reinforced nickel aluminide matrix in situ composites were produced using a newly patented laser melting furnace. Microstructure of the laser melted TiC/(Ni3Al–NiAl) in situ composites was characterized by optical microscopy (OM ...

Rhodium and Hafnium Influence on the Microstructure, Phase Composition, and Oxidation Resistance of Aluminide Coatings

Metals, 2017
A 0.5 μm thick layer of rhodium was deposited on the CMSX 4 superalloy by the electroplating method. The rhodium-coated superalloy was hafnized and aluminized or only aluminized using the Chemical vapour deposition method.

Reactive Nanoparticle Composed Bilayers: An Alternate Route Toward the Production of Pt/Al Nanofoils

Small, Volume 22, Issue 12, 25 February 2026.
Spark ablation‐assisted gas phase electrodeposition is an alternate route toward Pt/Al self‐propagation reactive system synthesis. Pt film morphology‐dependent reaction kinetics is a significant advantage. Low spark power and gas flow rate produce porous films and slow speeds, while high power and flow rate give three orders of magnitude faster ...

The Role of Substrate Surface Roughness on in-Pack Aluminization Kinetics of Ni-Base Superalloy

Journal of Manufacturing and Materials Processing, 2020
The Ni-base superalloys facing high temperature require further protection against high temperature oxidation. One of the most common methods providing high temperature oxidation resistance is the production of aluminide layers (NiAl-coatings).

Nanoindentation Properties of Ti‐yAl‐Mo Fabricated via Plasma Activated Sintering

Micro &Nano Letters, Volume 21, Issue 1, January/December 2026.
Ti‐yAl‐1Mo alloys were synthesised via plasma‐activated sintering, achieving near‐full densification and predominantly α‐Ti microstructures. Nanoindentation revealed strong composition‐dependent improvements, with Ti‐7Al‐1Mo showing more than double the hardness of commercially pure titanium.

Formation and Evaluation of Oxidation Behavior of Zirconia- Aluminide Coating on Nickel- Based Alloy

Journal of Advanced Materials in Engineering, 2020
Practical applications of thermal barrier coatings with aluminide bond-coats are limited due to oxide scale spallation of the aluminide coating under applied thermal stresses.
