The report presents the investigation of a possibility of an application of pulse concentrated energy fluxes for the
 creation by shock alloying method of pseudo-solid solutions of metals, which interact chemically with each other
 neither in solid nor in liquid states. As an example of such compounds a system W-Cu was chosen. The experiments
 were conducted by use of plasma focus facility PF-4 (Installation "TYULPAN") in Lebedev Physical Institute. In the
 work it was found that the copper plate was welded with the high degree of adhesion to tungsten. The nature of the
 penetration of chemically neutral atoms of Cu in material of a target (W) is connected probably with two processes –
 the energy transfer to atoms from concentrated pulse fluxes of energy and the initiation of shock waves and their
 propagation in the target material.
