    Oxide dispersion-strengthened alloy - Wikipedia

    • Oxide dispersion strengthened alloys (ODS) are alloys that consist of a metal matrix with small oxide particles dispersed within it. They have high heat resistance, strength, and ductility. Alloys of nickel are the most common but includes iron aluminum alloys. Applications include high temperature turbine blades and heat exchanger tubing, while steels a… See more

    Mechanism

    Oxide dispersion strengthening is based on incoherency of the oxide particles within the lattice of the material. … See more

    Synthesis

    ODS steels creep properties are dependent on the characteristics of the oxide particles in the metal matrix, specifically their ability to prevent dislocation motion as well as the size and distribution of the particles. Hoelzer an… See more

    What are the mechanical properties of ODS alloys?
    The mechanical properties of ODS alloys are governed by the mechanism of solid solution hardening, which is mainly determined by the chemical composition of the matrix alloy, and by dispersion hardening caused by the dispersion of oxide nanoparticles in the matrix alloy , particularly in the vicinity of grain boundaries.

    What are additively manufactured ODS alloys?
    Today, additively manufactured ODS alloys are characterized by inferior mechanical properties compared to conventionally produced ODS alloys. Consequently, the powder composite manufacturing techniques and additive manufacturing process design must be adjusted towards homogeneous dispersions of extremely fine nanoparticles.
