Determination of metal foam flow conditions at a temperature higher than the liquidus temperature

Grabian J.

Archives of Foundry Engineering

2011

Vol. 11, iss. 1

27-30

As it is known a foam made of composite with aluminium alloy matrix and SiC particles reinforcement does not reach the liquid state even at a temperature over 1000oC. The causes of such behaviour of foam have been examined. It has been found that it is due to two phenomena. One is connected with the creation of continuous layer of oxides at the boundary of gaseous pores and liquid metallic phase. The other is an increase of the apparent viscosity of solids suspended in liquid metal along with an increased content of these inclusions to the point where the suspension loses its continuity.
