Figure 1

Phases identification and microstructures of the 16.4% AlNp/Al composites.

(a,b) SEM images at low magnification show the typical dispersion of the phases. (c) XRD analysis reveals the main secondary phases: AlN and AlB2. The weaker peak amplitude of AlN is due to the low content. (d) EDS result of the irregularly gray particle is taken on the pointed dot in its top inset of 16.4% sample image. (e) HRTEM image of nano-scale AlNp shows the clean interface with Al matrix. (f) EELS pattern that verifies the existence of N element in the particle shown in e.
