Conclusions

  1. 1.

    The primary crystallization structure of Mo-W alloys can be observed by scanning-electron microscopy. It could not be revealed by other methods. The main constituents of this structure are cells and cellular dendrites.

  2. 2.

    The primary dendritic axis has a variable chemical composition along its length, which is caused by its discontinuous growth.

  3. 3.

    There is an interrelationship between the primary crystallization structure and the degree of the intracrystalline segregation, which develops more intensively for cellular growth than when cellular dendrites are formed.

  4. 4.

    Variation in the boron content in alloys of the Mo-W system almost does not have any effect on the degree of development of intracrystalline segregation of W in Mo.
