Hydrogen solubility in zirconium intermetallic second phase particles

, 2013
The enthalpies of solution of H in Zr binary intermetallic compounds formed with Cu, Cr, Fe, Mo, Ni, Nb, Sn and V were calculated by means of density functional theory simulations and compared to that of H in {\alpha}-Zr. It is predicted that all Zr-rich

Tribological Performance of 60NiTi Alloy Under Varying Contact Conditions and Elevated Temperatures in Linear Reciprocating Sliding

Advanced Engineering Materials, EarlyView.
This study investigates the tribological response of 60NiTi alloy under dry, water‐lubricated and high‐temperature conditions. The alloy exhibits decreasing wear volume and friction with increasing temperature due to the formation of protective oxide layers. The work clarifies dominant wear mechanisms and demonstrates the suitability of 60NiTi for high‐

Characterization of a Recyclate‐Based MgO‐Steel Composite As‐Sintered Inert Anode Candidate After Exposure to Cryolite Electrolysis

Advanced Engineering Materials, EarlyView.
Carbon‐free inert anodes are essential for decarbonizing aluminum electrolysis. This study investigates a recyclate‐based MgO‐316L steel composite anode tested under galvanostatic Hall–Héroult conditions in cryolite at 1000°C. Microstructural analysis reveals selective MgO fluorination, spinel and oxide layer formation, electrolyte infiltration, and ...
