Paper Abstract

We report on the production of thin films of titanium nickelides (TiNi) shape memory alloy, prepared via Current- Activated Tip-based Sintering (CATS), a new localized powder sintering process. Mechanically alloyed equi-atomic TiNi powder was tip-sintered at varying currents and cycles of current exposure time. The effect of processing conditions on the developed localized microstructure and properties are discussed. The number of cycles of current exposure time and current magnitude were studied. Both number of cycles and current magnitude in general result in an increase micro-hardness and a reduction in residual porosity in the sintered thin films.
