Microstructure and mechanical property of in situ synthesized multiple-reinforced (TiB+TiC+La2O3)/Ti composites

Creep rupture property of in situ synthesized (TiB+La2O3)/Ti composite

“…The composite has a little increase in percentage elongation. As discussed in paper [19], dispersed small particles and decreasing of oxygen content in the matrix can increase the plasticity. In this composite, the plasticity is surely increased because dispersed La 2 O 3 particles were very fine and small (mainly in nano-size) and the oxygen content in the matrix was dramatically decreased by the addition of the LaB 6 based on the reaction (1).…”

“…In this work, (TiB + La 2 O 3 )/Ti TMC were synthesized in a novel in situ process [17][18][19] based on the reaction between Ti, LaB 6 , and oxygen in the raw materials as following:…”

Microstructural characterization and mechanical properties of TiC/near-α Ti composite obtained at slow cooling rate

“…In terms of the reinforcements in TMCs, TiC has been considered as one of the effective reinforcements since TiC with excellent properties can be compatible with Ti matrices [5][6][7]. Combustion assisted cast (CAC) have been widely used to fabricate in situ synthesized TMCs due to its obvious advantages such as direct casting forming, simplicity, the low fabrication cost and excellent interfacial system [8][9][10].…”

Superplasticity of coarse-grained (TiB+TiC)/Ti–6Al–4V composite

“…In situ synthesized discontinuous-reinforced TMCs have attracted great attention because of their strong matrix-reinforcement bond, little contamination, ease of fabrication, and low cost [3][4][5][6][7][8][9][10][11][12][13][14]. The in situ synthesis methods include self-propagation high-temperature synthesis (SHS) [3,4], powder metallurgy (PM) [5][6][7], mechanical alloying (MA) [8], rapid solidification process (RSP) [9,10], ingot metallurgy (IM) [11][12][13][14], etc. TiB and TiC particulates have been considered as the two best reinforcements in the titanium matrix due to their high elastic modulus, high thermal stability, similar density with titanium alloys, and excellent interfacial bonding with titanium matrix [11].…”

The mechanical properties of in situ TMCs were enhanced significantly.…”
