What is ODS Aluminum?
ODS aluminum (oxide dispersion strengthened aluminum) is a class of high-performance aluminum materials whose overall properties are enhanced through powder metallurgy and oxide dispersion strengthening.
Oxide films can hinder densification during aluminum powder sintering. ODS aluminum addresses this issue through activated sintering: activating agents and dynamic reactions during sintering help break up the oxide films, promoting high densification and nanoscale oxide dispersion strengthening.
This material design produces a finer, more uniform microstructure and improves the overall strength, thermal stability, and manufacturability of complex structures.
