Determination of mechanical properties in multiphase bodies of extraterrestrial origin is a fundamental task. In this work the hardness and Young’s modulus in the Seymchan pallasite were determined in kamacite α-Fe (Ni, Co), taenite γ-Fe (Ni, Co), plessite (α+γ), tetrataenite FeNi using nanoindentation technique. For the first time, the hardness and modulus of elasticity of a two-phase nanostructure of cloudy zone FeNi+α-Fe(Ni,Co), formed as a result of very slow cooling (about 1 K/Myr), was determined.

Keywords: Seymchan pallasite, indentation, Young’s modulus, hardness, Fe-Ni alloys, cloudy zone, tetrataenite.
