“…Recently developed spark and resistance sintering (SRS) or spark plasma assisted sintering [1][2][3][4] can produce machine parts with higher density at a lower sintering temperature within a shorter time than the normal sintering, the sintering after cold isostatic pressing (CIP) and the sintering during hot isostatic pressing (HIP). The applied pressure during SRS also contributes to the increase in the density of sintered parts.…”

Mixtures of Ti, Ni and TiB 2 , TiC or SiC powders were sparkand resistance sintered to obtain TiB 2 , TiC or SiC dispersed TiNi pseudoelastic alloy. The alloys were annealed, solution treated and aged after the sintering. Nano indentation tests, bending tests, and abrasion wear tests were carried out on these alloys. Nano indentation tests showed that the TiNi alloy and ceramics dispersed TiNi alloys exhibited larger displacement recovery than the reference materials such as steels and titanium alloy at the same indentation displacement. The solution treated and aged specimens exhibited larger displacement recovery than the annealed ones. Vickers hardness of the annealed alloys increased with increasing ceramics content, while relative density and bending strength decreased. TiB 2 dispersed TiNi alloy has higher hardness than TiC dispersed TiNi alloy and larger bending strength than SiC added alloy. Abrasive wear resistance of TiB 2 dispersed TiNi alloy was much larger than that of the steels and titanium alloys, which can be explained by the stress relaxation of pseudoelastic matrix surrounding ceramics particles. In addition, the TiNi alloys annealed after sintering exhibited better wear resistance than the solution treated and aged ones. The wear resistance of TiB 2 dispersed TiNi alloy was larger than that of TiC dispersed TiNi alloy perhaps because of larger interfacial strength between TiB 2 particles and TiNi matrix than that of TiC particles and TiNi matrix.
