Rapid synthesis of Ti alloy with B addition by spark plasma sintering

The Influence of a Small Boron Addition on the Microstructure and Mechanical Properties of Ti‐6Al‐4V Fabricated by Metal Injection Moulding

“…4(d)] was indexed during the EBSD experiments and no TiB 2 was observed in the Ti-6Al-4V-0.5B alloy. This is in agreement with thermodynamic expectations [17,[21][22][23][24] and with the Feng et al [20] statement.…”

“…Three boron compounds exist in the Ti-B system: TiB, Ti 3 B 4 , and TiB 2 . Feng et al [20] stated that only TiB can be synthesized in situ from the reaction between Ti powder and boron powder. In this investigation, only the TiB phase [ Fig.…”

Mechanical Behavior of Cryomilled Ni Superalloy by Spark Plasma Sintering

“…[11] In INCONEL 625 alloy consolidated using HIP, a density of 85 to 90 pct was obtained at a temperature of 1118 K. [12] Fast densification was also achieved with SPS in other material systems due to an acceleration of mass transport resulting from the presence of pulse currents. [13][14][15][16][17][18] To seal the porosity, the samples that were SPS consolidated at 1073 K were HP at 773 K (designated as SPS-HP hereafter) to full density corresponding to INCONEL 625 alloy (8.46 g/cm 3 ) at a deformation strain of~8 pct (Figure 1(c)). The fully dense sample SPS-HP yielded a similar yield stress compared to the ones SPS consolidated at higher temperatures (SPS-1173 and SPS-1273), as seen in Figure 1(b).…”

Defects formation of the in situ reaction synthesized TiB whiskers

“…The blended powders were first ball-milled for 10 h in argon atmosphere, and then hot pressed sintering in vacuum at 1000-1300 1C for 1 h with a pressure of 20 MPa. The TiB reinforcement can be obtained by the chemical reaction between Ti and B during the sintering process [13]. TiB whiskers were separated from the composites by the electrodissolution method and collected.…”
