• Tetrataenite - Wikipedia

    en.wikipedia.org/wiki/Tetrataenite Tetrataenite is a native metal composed of chemically-ordered L1 0-type FeNi, recognized as a mineral in 1980. The mineral is named after its tetragonal crystal structure and its relation to the iron-nickel alloy, taenite. It is one of the mineral phases found in meteoric iron.

    www.minsocam.org/ammin/AM65/AM65_624.pdf Tetrataenite is a new meteoritic mineral with ideal formula FeNi, which forms by ordering of Fe and Ni atoms in taenite. Albertsen et al. (1978a), us,ing Mdssbauer spectroscopy and X-ray diffraction, identi-fled ordered FeNi in two iron meteorites. They found it has the Ll6 (or

The Fe-Ni alloy minerals commonly found in meteorites 31 are kamacite and taenite. Kamacite is characterized by a relatively low Ni-content (< 7 wt. %)

    www.sciencedirect.com/science/article/pii/S0304885317324095 FeNi L1 0 (tetrataenite) phase has great perspectives for hard magnetic materials production. In this paper we report on synthesis of this phase in chemically co-precipitated FeNi nanopowder by means of a thermal treatment procedure which includes cycling oxidation and reduction processes at 320 °C.
