Dc. Jia et al., Effect of SiC particulates on the microstructure of Al-6Ti-6Nb matrix composites fabricated by mechanical alloying technique, J MAT SCI T, 17, 2001, pp. S61-S64
Millimeter sized SiC (m-SiCp) and nanometer sized SiC (n-SiCp) particulates
reinforced Al-6Ti-6Nb matrix composites were prepared by mechanical alloyi
ng (MA) and later hot-press sintering. Their microstructure was investigate
d to know the influence of the incorporated SiC particles. The secondary Al
3Ti, AlNb2 intermetallics particle size, the Al matrix grain size and their
submicrostructure are strongly affected, and they are correlated with the
thermal stability of the composites.
