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.

Parameter Variation in Planetary Ball Milling of Titanium Aluminide Powder in XHV‐Adequate Atmosphere

Advanced Engineering Materials, Volume 28, Issue 12, 17 June 2026.
This study investigates the effects of milling parameters, including rotational speed, milling duration, and ball‐to‐powder ratio, on TiAl particle size and morphology in an XHV‐equivalent atmosphere. The creation of oxide‐free surfaces enhances the mechanical properties of green bodies.

Deoxidation of Titanium Aluminides.

DENKI-SEIKO[ELECTRIC FURNACE STEEL], 1993
The deoxidation of TiAl is one of the key technologies to recycle the scrap contaminated through the casting processes. Fairy high amount of aluminum, more than 30%, enables the few deoxidation methods such as evaporation of aluminum oxide or Ca addition, while they are inapplicable to conventional Ti-alloys containing lower aluminum.The TiAl with 0.21%
