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.

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.

Advanced Engineering Materials, Volume 27, Issue 24, December 2025.This work reveals the phase composition and quantitative morphology analysis of precipitation‐hardened Fe32Cu12Ni11Ti16Al29 complex‐concentrated alloy. The precipitates are shown to have a high coherency. Morphology transition between sphere, cuboidal, and elongated morphology is observed. Finally, the overaging behavior is captured using microhardness.
