Abstract
The determination of residual stresses, RS, in 6061Al-15 vol % SiCw composites was carried out to correlate them with whisker orientation, distribution and aspect ratio. The composites were obtained by a powder metallurgical, PM, route and consolidated by extrusion at four different temperatures, Textr. This is the main parameter affecting the whisker orientation/ distribution; an increase in Textr leads to an increasing whisker alignment with extrusion axis. The results of the sin2ψ plots account for a non-hydrostatic stress state in all composites. This is expected because of the deviatoric component of the RS tensor generated by the whisker geometry. The RS can explain the strength differential effect, SDE, observed in uniaxial testing (tensile versus compressive behaviour) of these composites.
