Figure 13. The bottom view of a Cu-10.5Ti sessile drop on a BNlub coated graphite substrate after interaction at 1,373 K showing cracks due to chemical interactions. The interaction is very strong and is accompanied by fast spreading of the droplet even outside of the (top) schematically illustrated substrate (N. Sobczak, unpublished data).
