Abstract
The in situ fabrication of titanium carbide reinforced copper and aluminium bronze (AB2) composites by carbothermal reduction of titanium in an induction furnace has been investigated. An inert atmosphere was maintained with carbon monoxide created as a byproduct from the heat of reaction between the induction field, graphite crucible and graphite lid. Titanium carbide particles of the order 1–3 μm were formed in aluminium bronze at approximately 1250°C and, in copper, particles of order 1–6 μm were produced at approximately 1330°C. Dispersion concentrations of titanium carbide of 20% and 6.5% were obtained for copper and aluminium bronze respectively. In addition, evidence is presented indicating that iron could be used as a dispersion medium for titanium carbide particulates in aluminium bronze alloys.
