Determination of residual stress by neutron diffraction in 6061Al-15 vol.%· SiCw composites with different whisker orientation/distribution

The determination of residual stresses, RS, in 6061Al-15vol%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, Text....
