Crystalline nanowhiskers (NWs) composed of fullerene C-60 and C-70 molecules, i.e., alloy NWs, were synthesized by a liquid-liquid interfacial precipitation method. The nominal composition of C-70 ranged from 0 to 40 mass%. The bending tests of the alloy NWs were performed inside a highresolution transmission electron microscope, and the deformation behavior was observed in situ. The bending force acting on the NWs were measured simultaneously by an optical deflection method, and the Young's modulus was estimated from the resulting force-flexure curves. The average Young's modulus was found to increase to approximately 30 GPa as the C-70 composition was increased to the solubility limit. In contrast, the Young's modulus decreased with increasing NW diameter caused by the addition of C-70.
