  2. Oxide dispersion-strengthened alloy - Wikipedia

    en.wikipedia.org/wiki/Oxide_dispersion...

    For γ’ volume fractions of 0.4 to 0.6 in nickel-based alloys, the threshold stress for local climb is only about 1.25 to 1.40 times higher than general climb. [ 8 ] Dislocations are not limited to either all local or all general climb as the path that requires less energy is taken.

  3. Selective laser melting - Wikipedia

    en.wikipedia.org/wiki/Selective_laser_melting

    SLM-based additive manufacturing of nickel superalloys still poses significant challenges due to these alloys’ complex composition. With multiple alloying elements and high aluminum/titanium fraction, these materials, when consolidated through SLM form various secondary phases, which affects the processability and leading to weakness within ...

    en.wikipedia.org/wiki/Mechanical_alloying

    Originally developed to produce oxide-dispersion strengthened (ODS) nickel- and iron-base superalloys for applications in the aerospace industry, [1] MA has now been shown to be capable of synthesizing a variety of equilibrium and non-equilibrium alloy phases starting from blended elemental or pre-alloyed powders. [2]

    A wide range of engineering alloys are compatible with the EBDM process and are readily available in the form of welding wire from an existing supply base. These include, but are not limited to, stainless steels, cobalt alloys, nickel alloys, copper nickel alloys, tantalum, titanium alloys, as well as many other high-value materials. [citation ...

  6. Superalloy - Wikipedia

    en.wikipedia.org/wiki/Superalloy

    A superalloy, or high-performance alloy, is an alloy with the ability to operate at a high fraction of its melting point. [1] Key characteristics of a superalloy include mechanical strength , thermal creep deformation resistance, surface stability, and corrosion and oxidation resistance.

  7. Inconel - Wikipedia

    en.wikipedia.org/wiki/Inconel

    Inconel alloys are oxidation- and corrosion-resistant. When heated, Inconel forms a thick, stable, passivating oxide layer protecting the surface from further attack. Inconel retains strength over a wide temperature range, attractive for high-temperature applications where aluminum and steel would succumb to creep as a result of thermally ...
