Correlation between phase evolution, mechanical properties and instrumented indentation response of TiB2-based ceramics

Effect of SPS parameters on densification and properties of steel matrix composites

“…These benefits make SPS suitable for the development of many innovative materials difficult to be produced by traditional methods, such as ceramics [15,16], nanocrystalline materials [17,18], functionally graded materials [19] and composites [20][21][22] Ceramic materials, such as carbides and borides, are candidates for advanced strengthening phase in steel matrix composites due to their exceptional hardness and stability with the steel matrix. Titanium diboride (TiB 2 ) also exhibits many unique physical properties such as high hardness, good electrical and thermal conductivities, high melting point, chemical stability, and high wear resistance [23,24]. Li et al [25] synthesized TiB 2 reinforced Fe matrix composite using SPS technique and obtained a maximum density of 98.6% after sintering for 5 min.…”

Microstructural development and mechanical properties of hot pressed SiC reinforced TiB2 based composite

“…Therefore, the major challenge in the processing of TiB 2 is the poor sinterability and in order to achieve a fully dense ceramic with desirable microstructure, high sintering temperatures along with applying pressure on the powder compact are needed. Many approaches for increasing the sintering driving force of this material have been attempted, including pressureless sintering, hot pressing and spark plasma sintering [11][12][13][14][15][16][17][18][19]. Furthermore, the published results indicate that incorporation of ceramic sinter-additives such as TiC, Al 2 O 3 , B 4 C, MoSi 2 .…”

Influence of Sintering Temperature on the Microstructure of TiB₂ Sintered with Al₃Ti Additive

“…However, the Hv value of TiB 2 sintered at 1573 K is 800 which is considerably lower than the reported Hv value, 3400, of TiB 2 sintered at 2073 K by hot pressing. 7) This implies that sintering proceeds scarcely at 1573 K, probably because the sintering temperature is too low in comparison with the melting temperature of TiB 2 . The Hv of TiB 2 sintered with 10 and 20% Al 3 Ti increases as the sintering temperature increases.…”
