Figure 4From: A large-scale fabrication of flower-like submicrometer-sized tungsten whiskers via metal catalysisEDS patterns of the Fe element segregation structures formed in the experiment. (a) The aggregation structure formed by sintering; (b) the flake structure formed by Fe element segregation. ZAF, Z is atomic number correction factor, A is absorption correction factor, and F is fluorescence correction factor.Back to article page
