NICKEL-BASED MULTILAYER COMPOSITE REINFORCED BY INTERMETALLIC LAYERS
Ni/Al-microcomposites were produced by diffusion welding of multilayer packets under pressure. The intermetallics of Ni<sub>3</sub>Al and NiAl were formed in the composite after heat treatment resulting in reactive diffusion. The composite material consisting of the layers of enough ductile solid solution of aluminium in nickel and the hardening intermetallic phase of Ni<sub>3</sub>Al has been produced.
