Abstract

The interfacial criterion to avoid pushing of particles during solidification of ceramic reinforced metal matrix composites (MMCs) at low rates of the solidification has been found as: i. for liquid alloys with at least one interface-active solute (at the melt/particle interface) the engulfment of particles is always ensured by the interfacial energy gradient caused by solute build-up; ii. for pure metals and for alloys with no interface-active components engulfment is ensured if the following condition is fulfilled: Δσ = 2σcsclsl2, and lower indexes indicate the phases in contact: `c' is for ceramic particle, `s' is for solid metal and `l' is for liquid metal). A new model is derived to estimate the interfacial energy between solid metal and solid ceramics. Based on this model, the pushing-engulfment diagrams have been constructed.
