Investigation of the Phase Composition of the Diffusion Zone in the Al-Ni-Cr Composite Material

This paper describes the investigation of the phase composition of the diffusion zone in the H20N80+AD1 composite material obtained by explosion welding, after heat treatment at 630оС, 75h. The isothermal section of the Al-Cr-Ni state diagram at room temperature is given. Microhardness of diffusion zone layers is measured.
