Abstract

Nickel aluminides have shown great potential as high temperature structural materials. In this study, two classes of nickel aluminide were reinforced with 0.5wt% MWCNTs. Starting powders of nickel, aluminium and MWCNTs were ball milled together using a two stage milling regime and consolidated by spark plasma sintering. The effect of MWCNT reinforcement on the hardness of two classes of nickel aluminide was investigated. Microhardness values revealed a lack of dependence on densification for the NiAl3 composites. The microhardness values of NiAl-CNT reduced with MWCNT addition whereas microhardness values of NiAl3-CNT increased with MWCNT addition.
