SUMMARY Dislocation networks in tungsten carbide (WC) have been studied in the HVEM. The nodes of the network have been resolved by using the weak‐beam technique in the high voltage electron microscope. They consist of parallel partial dislocations, which are concluded to have Burgers vectors of the type b = 1/6 <20<23>.
