Extended Data Fig. 6: Comparison of fracture toughness values from SENB and indentation measurements for Y-PSZ, pure nt-diamond and nt-diamond composite.
From: Hierarchically structured diamond composite with exceptional toughness
SENB, filled bars; indentation, empty bars. The loads for indentation fracture toughness measurement were 49 N for Y-PSZ, and 19.6 N for pure nt-diamond and nt-diamond composite. Error bars indicate 1 s.d. (n = 5 for Y-PSZ and nt-diamond composite, n = 3 and 5 for indentation and SENB measurements of pure nt-diamond, respectively). ntD, nt-diamond.
