It has been shown experimentally that the effect of ultrasound during heat treatment of the explosion-welded bimetal nickel NP2 + aluminum AD1 helps to reduce the latent nucleation period of NiAl and NiAl intermetallic layers at its interlayer boundary, reduces the temperature of the onset of eutectic transformation (~10 °C), at a temperature of intense diffusion increases the thickness diffusion zone (by 30-40%), without affecting its phase and chemical composition.
