| Abstract: | The effects of some process conditions on the porosity of the NiAl castings produced by a centrifugal combustion synthesis has been investigated. In the centrifugal combustion synthesis experiments, a green compact of reactants consisting of Al, Ni and NiO was set in an alumina container in a centrifugal caster and was ignited to produce a molten NiAl by the following reaction: (This article is not displayable. Please see full text pdf.) \ oindentAdiabatic combustion temperature of the reaction can be varied arbitrarily by changing the value of a. The molten NiAl was then solidified in the alumina container under centrifugal force. The porosity in the present study was designated by an area percent of macroscopic pores measured on the longitudinal cross section of the specimens. The results are summarized as follows:
(1) The relative density of the green compact has no influence on the porosity of the cast NiAl.
(2) The porosity decreases as the value a increases.
(3) The application of centrifugal force is effective for the reduction of porosity. |
