Interaction of amorphous fullerene C 60 with austenite Fe–Ni alloy at high temperatures and pressures

摘要: Abstract Interaction of amorphous fullerite C60 with austenitic Fe-33.2 wt.% Ni alloy at pressures 0–8 GPa and temperatures 600–1100 °C was studied by neutron diffraction. The obtained ball milling mixed the powder crystalline alloy. interaction sintering led to dissolution carbon in fcc Fe–Ni solid solution formation carbide (Fe, Ni)3C, but Fe–Ni–C did not undergo phase transformations preserved original structure. As a result, hardened, we could also witness clear barometric effect: pressure 2 GPa amount dissolved carbon, hardness micro- nanoindentation turned out be significantly higher than those 8 GPa. During is undergoing transitions its microhardness metal component. At high graphite appears. presence composite reduces temperature comparison pure fullerene.
