Laser synthesizing NiAl intermetallic and TiC reinforced NiAl intermetallic matrix composite [PDF]

Journal of Laser Applications, 2004
The NiAl intermetallic layers and NiAl matrix composite layers with TiC particulate reinforcement were successfully synthesized by laser cladding with coaxial powder feeding of Ni/Al clad powder and Ni/Al+TiC powder mixture, respectively. With optimized processing parameters and powder mixture compositions, the synthesized layers were free of cracks ...

Layered NiAl/Cu/NiAl Composite by SHS in a Mode of Frontal Combustion

International Journal of Self-Propagating High-Temperature Synthesis, 2020
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.
