the critical role of carbon in marrying silicon and graphite

Ductile Iron Data

Density is affected primarily by the percentage of graphitized carbon, with densities varying from 6.8 g/CM 3 to 7.4 g/CM 3 for high carbon ferritic and low carbon pearlitic irons respectively. The density of a typical cast steel - 7.8 grams/CM 3 - is almost 10 per cent higher than that of Ductile Iron.

The Role of Sliding Contact in Nanoscale

Results from sliding of nanoscale silica asperities against highly-oriented pyrolytic graphite (HOPG) and hydrogen-doped tetrahedral amorphous carbon (a-C:H) surfaces are consistent with this model. This contrasts with the directly-proportional adhesion-speed behavior observed in the in situ transmission electron microscopy experiments of silicon and diamond.

The carbon content of Earth and its core

Carbon is critical to life on Earth, climate regulation, and many geological processes. Despite its importance, the amount of carbon in the planet has been poorly understood due to uncertainty in the composition of Earth's core, likely the largest reservoir of carbon.

Ductile Iron Data

Graphite shape, which can range from flake to spherical, plays a significant role in determining the mechanical properties of cast irons. Figures 2.4 and 2.5 show that graphite flakes act like cracks in the iron matrix, while graphite spheroids act like crackarresters, giving the respective irons dramatically different mechanical properties.
