Combustion Synthesis of Metal-Intermetallic-Ceramic Laminate AlMg6-NiAl-TiC Composite

In this study, SHS was used to produce metal-intermetallic-ceramic laminate AlMg6-NiAl-TiC composite. The experiment conducted without a cylindrical powder pellet holder produced no joint between the NiAl and AlMg6 sheet. On other hand, inside (CPPH) with blind hole joint. It found that sheet had temperature of 400–550 °C across its entire thickness during SHS. study microstructure energy-dispersive analysis (EDS) composite showed it five layers: (1) ceramic layer 7-mm-thick TiC; (2) upper diffusion formed at interface TiC consisted + NiAl; (3) an intermetallic layer, which 13-mm-thick (4) lower AlMg6; (5) 4-mm-thick aluminum alloy AlMg6. EDS synthesis interaction surface sheet, mixing components initial materials (NiAl, AlMg6) in occurs. At AlMg6, microhardness 790–870 HV, indicates presence quenching structures melted zones.
