Interaction between Fе–Ni Austenitic Alloy and Minor Amounts of Mechanically Milled C60 Fullerene at High Temperatures and Pressures

The sintering of Fe–Ni austenitic alloy at 4.5 GPa, 900°C and 8 GPa, 800°C with mechanically milled fullerene C60, 1.7 at % results in the dissolution of carbon in the FCC lattice of the alloy, and the formation of carbides and isolated regions containing fine powder mixes of the alloy and carbon phase. The microhardness of these regions is twice as high as that of the alloy.
