A psychophysical experiment was performed to measure the visibility of chromatic noise. Through Principle Component Analysis (PCA) on the results of this experiment, an orthogonal color space with the luminance channel independent of chromatic channels was constructed. By transforming noise images into this space, the visibility of chromatic noise can be(More)

Keywords: Grain boundary Cemented carbide Sintering Electron microscopy Five parameter analysis a b s t r a c t The effect of the densification mechanism on the S2 grain boundary plane distribution was investigated in WC–Co composites. Specimens were prepared separately by sintering in hot isostatic press (sinter-HIP) and spark plasma sintering (SPS). It(More)
The effect of coherency WC/Co phase boundaries on the fracture toughness of the nanocrystalline WC-Co cemented carbides is studied by MD simulation method. The simulation results show that the nanocrystalline WC-Co cemented carbides with coherency WC/Co phase boundaries has higher fracture toughness than that without coherency WC/Co phase boundaries.(More)
a r t i c l e i n f o The average interface area aspect ratios of carbide grains in WC–Co composites are measured from basal-to-prismatic area ratios determined by the five parameter analysis (FPA) method. Grain boundary plane distributions regardless of misorientations indicate that the (0001) basal and 1010 prismatic planes are the most common habit(More)
