Fig. 4.15. STEM images

Fig. 4.15. STEM images in bright field mode (a,c) and in Z-contrast (b,d) together with typical electron diffractograms of WC1-x (e) and W2C (f) of 9% W film annealed at 1450K [18]. Fig. 4.16. STEM images in BF mode (a,c) and in Z-contrast (b,d) together with typical electron diffractograms of WC1-x (e) W2C (f) and WC (g) of 18% W film annealed at 1450K [18]. - 48 -

In the 2200K, the majority of the crystals belong to WC, whereas the amount of W2C has reduced. The amount of WC1-x found in both samples does not vary much during both heat intervals. The small amount of WC1-x found clarifies the reason WC1-x is not found within the XRD diffractogram. Within the 2800K sample, both W2C and WC1-x have disappeared and changed into WC. Fig. 4.17. STEM images in BF mode (a,c) and in Z-contrast (b,d) together with typical electron diffractograms of WC1-x (e) W2C (f) and WC (g) of 18% W film annealed at 2200K [18]. The reason for the appearance of all three carbide may be the result of a concentration gradient found within the sample (figure 4.10b). Further research is still done on this sample. A hypothesis is that the WC1-x is found in the lower concentrated part of the sample, in the middle a mixture of W2C and WC could be found, whereas at top only WC may be found. - 49 -
