Figure 1From: HighP–T Nano-Mechanics of Polycrystalline NickelX-ray diffraction patterns of nanocrystalline (upper panel) and microcrystalline Ni (lower panel) at 298 K and selected pressures. The minor peaks around d-spacing values of 1.3 and 1.5 Å are lead (Pb) fluorescence linesBack to article page
