摘要：
The existence of micropores in the structure of WC-Co alloys located at the grain and phase boundaries and commensurate with an interlayer of a cobalt phase has been established using scanning electron microscopy. It has been shown that the micropore size and shape change with a change in sizes of they cobalt interlayer and tungsten carbide grains.
