In situ preparation of (TiB + TiC + Nd2O3)/Ti composites by powder metallurgy

In situ reaction synthesis of Ti–TiB composites containing high volume fraction of TiB by spark plasma sintering process

“…Considerable research has been carried out on the Ti-TiB composites with TiB up to about 30 vol%, using techniques such as casting, vacuum arc remelting, powder metallurgy, combustion synthesis, rapid solidification processing, and direct laser cladding [20][21][22][23][24][25][26][27]. Limited data is available on the microstructures and mechanical properties of the Ti-TiB composites with high volume fraction of TiB [28,29].…”

The Influence of B₄C on the Fluidity of Ti-6Al-4V-<i>x</i>B₄C Composites

“…14) In recent years, there are many in situ techniques to synthesize TMCs, such as mechanical alloying, 5) powder metallurgy 6) and solidification process. 7) Traditional ingot metallurgy plus self-propagation hightemperature synthesis reaction between titanium and B 4 C has become a popular method to fabricate TiB and TiC reinforced TMCs due to its low manufacturing cost and high efficiency.…”

Fabrication and mechanical properties of in situ TiC/Ti metal matrix composites

“…The interest in discontinuously reinforced titanium matrix composites (TMCs) has increased in recent years due to the low cost, easy fabrication and excellent mechanical properties [1][2][3][4]. Several ceramic particles were proposed as reinforcements [1][2][3][4][5][6][7]: SiC, TiN, TiC and TiB.…”

“…Several ceramic particles were proposed as reinforcements [1][2][3][4][5][6][7]: SiC, TiN, TiC and TiB. Of these TiB and TiC are the most frequently used [1][2][3][4]7]. The mechanical properties of TMCs have been found to be mainly dependent upon the composition and the microstructure of both the matrix and the particles.…”

“…The in situ synthesis is an effective method to enhance the bonding between particle and matrix by formation of a clean interface. Recently several processing techniques for synthesizing the in situ ceramic reinforcements have been developed, including reactive sintering [2,3,8], mechanical alloying [9], casting [10] and gas-solid reaction [11]. The reactive sintering process seems to be a promising way to fabricate TMCs due to its low-cost and simplicity.…”
