Thermal expansion of high-silicon cast iron

Tribological Behavior of Reinforced and Unreinforced High Chromium Cast Iron

In this paper, the metal matrix composites containing 22 wt % Cr, 2.5 wt % C and 2 to 16  volume percent TiC were processed by solidifying Fe-Cr-Ti-C in which precipitation of titaniumcarbide and chromium carbide occurred. The microstructure and abrasion resistance of in-situ synthesized composites were compared with the unreinforced high chromium white cast iron (HCWCI) containing 22 w. t. % C...

Mechanism of silicon influence on the chill of cast iron

In this work an analytical solution of general validity is used to explain mechanism of the silicon influence on the absolute chill tendency (CT) and chill (w) of cast iron. It is found that CT can be related to nucleation potential of graphite (Nv), growth parameter (μ) of eutectic cells, temperature range (∆Tsc) and the pre-eutectic austenite volume fraction (fγ). It has been shown that silic...

Electrical and thermal transport properties of iron and iron-silicon alloy at high pressure

[1] The efficiency of heat transfer by conduction in the Earth’s core controls the dynamics of convection and limits the power available for the geodynamo. We have measured the room temperature electrical resistivity of iron and iron-silicon alloy to 60GPa and present a new model of the resistivity at high pressures and temperatures relevant to the Earth’s core. The model is compared with avail...
