Figure 1: Characterization of Ni/Al2O3 surface.

From: Nanoparticle-induced unusual melting and solidification behaviours of metals

Figure 1

Scanning electron microscopy (SEM) images before (a) and after (b) laser melting at a pulse energy of 0.18 mJ. The bright granular phases are the Al2O3 nanoparticles while the continuous dark phase is the Ni matrix. The nanoparticles are well dispersed and uniformly distributed in the matrix. Scale bars, 1 μm in a and 2 μm in b.
