Cermets based on transition metal borides, their production and use

Process of production of a separate phase, especially a solid phase of modified composition, from a matrix in liquid phase. Starting at a temperature at which the matrix is entirely molten, it is subjected to the action of an electromagnetic field, with such a frequency that the induced currents can be developed in the entire mass, and then the matrix is cooled, while maintaining the electromagnetic field, to a temperature range which causes the separation of a separate phase, especially a solid phase, and this phase is collected, under the effect of the electromagnetic field, in a certain zone of the matrix in the form of a compact mass.
