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 ...

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.

Time‐resolved imaging of electron beam powder bed fusion using an X‐ray microscope optimized for white beam radiation

Journal of Synchrotron Radiation, Volume 33, Issue 1, Page 181-194, January 2026.
A high‐speed X‐ray microscope design optimized for white beam synchrotron radiation enables real‐time in situ imaging of crack dynamics during electron beam powder bed fusion (PBF‐EB) of high‐Z materials. With high temporal resolution and 10 µm spatial resolution, the system reveals previously unobservable crack evolution behavior in Ni‐based ...

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.
