SEM analyses of W-Ti and W-V alloys produced by a powder metallurgy route have revealed the presence of Ti or V pools with different sizes and shapes. The larger pools have sizes between ~0.3 and several microns and are embedded between the matrix grains. The smaller Ti-rich (V-rich) particles, with sizes below ~0.3μm, are spherical and are dispersed inside the matrix grains. The characteristics of...
The development of a dispersion of nanoparticles in the W–1%Y 2 O 3 and W–1%La 2 O 3 (wt%) alloys processed by hot isostatic pressing have been investigated using small-angle neutron scattering. The analyses of the scattering data using the Beaucage unified approach reveal the presence of a bi-modal distribution of spherical scattering centers with sizes of less of...
