International journal of self-propagating high-temperature synthesis Vol. 29, № 2. P. 104-107Abstract: SHS of layered NiAl/Cu/NiAl composite was studied experimentally and by mathematical modeling with special emphasis on critical conditions for combustion synthesis in (Ni–Al)/Cu/(Ni–Al) compacts. Our results may turn interesting to those engaged in fabrication of functionally graded materials.
As is known [1], functionally graded materials (FGM) can also be prepared by SHS joining of similar or dissimilar materials. Propagation of combustion wave formed in Ti–C–20% TiC mixture over a Ta tape was explored in [2]. Fabrication and simultaneous bonding of TiB2/Cu metal matrix composite with Al rod by combustion synthesis reaction was reported in [3]. Mathematical model for the penetration of a nonfusible obstacle by combustion wave was suggested in [4]. Numerical study on unsteady combustion in alternating fuel/inert layers was conducted by Krishenik et al. [5]: depending on process parameters, reaction could proceed in a mode of quasi-homogeneous or relay-race combustion. Prokof’ev and Smolyakov suggested a 2D model for combustion of thermally conjugated layers, including inert ones [6]. Good SHS joining was also achieved upon thermal explosion in (Ni + Al)/Nb/(Ni + Al + Nb) sandwiches [7].
In this communication, we report on the preparation of NiAl/Cu/NiAl composite by combustion synthesis in a mode of frontal combustion.
