Widmanstatten ferrite in lunar iron
Abstract
Fragments of lunar matter recovered by Luna 16 are subjected to metallographic analyses. Based on thermodynamic analyses, the specific nature of the Widmanstatten ferrite found in the high-iron lunar metal is discussed. The Widmanstatten microstructure of the iron-nickel lunar metal differs morphologically from the Widmanstatten structure found in meteorities. Chemical data indicate similar processes are responsible for the development of the structure in both lunar phase particles and in the metallic phase of meteorites.
