Creep Properties and Deformation Mechanism of Additively Manufactured NiAl‐CrMo Composites

Advanced Engineering Materials, EarlyView.
Additively manufactured NiAl‐CrMo composites contain numerous interfaces and cell boundaries that control their creep response. At 700°C under high applied stress, creep is dominated by dislocation‐controlled power‐law mechanisms. At 800°C–900°C and lower stresses, creep is primarily diffusion‐controlled along cell boundaries.

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.
