Zusammenfassung:Phase growth kinetics in the nickel-aluminum system has been studied within the range of temperatures equal to about 0.4-0.6 melting temperature of basic forming phase Ni sub 2 Al sub 3 . It is found that enhanced pressure induces acceleration of this intermetallic phase which is transformed in the course of time into NiAl. It is connected with perfection of interphase boundaries under pressure. Application of low hydrostatic pressures is a method for creation and maintenance of perfect diffusion contacts between adjacent layers.
