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.

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.

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 ...

Constitutive behavior and microstructural evolution in Ti–Al–Si ternary alloys processed by mechanical milling and spark plasma sintering

Journal of Materials Research and Technology, 2020
Severe plastic deformation is closely related to the microstructural behaviors of intermetallics or grain refinement by mechanical milling and subsequent rapid sintering process, i.e. high energy ball milling and spark plasma sintering.

Effect of Cyclic Heat Treatment on the Mechanical Properties and Microstructure of Al 6061 Alloy

Material Design &Processing Communication, Volume 2026, Issue 1, 2026.
This study investigates the influence of different cyclic heat‐treatment schedules on the mechanical behavior and microstructural evolution of Al 6061 alloy. Five identically sourced plates were subjected to controlled variations in quenching rate, aging temperature, and cooling conditions to establish a consistent microstructure–property relationship.
