Multilayer Ti–Ta–Ni–TiC–TiB Composite by Combustion-Aided Joining
2020
Multilayer Ti–Ta–Ni–TiC–TiB composite (cermet) was obtained by combustion-aided joining in multilayer sandwiches formed by Ti–C and Ti–B reactive layers and metal foils (Ti, Ta, Ni) and characterized by thermographic analysis and rapid video filming. Thin plates of resultant composite (32 × 14 × 1.5 mm) were formed within 0.2 s after ignition (burning velocity 195 mm/s). Ta foils were found strongly joined with Ti ones due to development of high combustion temperatures in the reactive layers yielding TiC and TiB ceramics. The presence of ceramics afforded for reducing material density, on retention of its heat/corrosion resistance. Our results open up new horizons for SHS-assisted fabrication of new refractory materials with required structure/properties.
