Synthesis of In-Situ Titanium Carbide Particle Reinforced Titanium Composites

Abstract

Titanium carbide particle reinforced titanium composites were prepared by in-situ synthesis reaction between titanium and carbon liquid alloys. The phases constitute and microstructures of titanium composite have been investigated by OM, XRD, SEM and EPMA. Although it was possible to synthesize titanium carbide particle reinforced titanium composites, the morphology of in-situ titanium carbide grows into typically dendritic shape due to the compositional supercooling theory. Using computerized image analysis, the average particle size and aspect ratio of in-situ formed titanium carbide is about 28.1 ㎛ and 1.9, respectively.

Precipitation Process of TiC in Low Alloy Martensitic Steel and Its Effect on Wear Resistance

“…The TiC particles were precipitated along the as-cast dendritic gap from the solute-rich site and were present as inclusions, which were relatively coarse. 16,17) The temperature of the large-sized TiC precipitated from the liquid in 0.7Ti was slightly higher than 0.3Ti with a mass fraction of 0.55%, while it is 0.05% in 0.3Ti, as shown in Fig. 6(c).…”

Synthesis and Characterization of Ti-TiB Composites Processed through Vacuum Sintering

“…Among these composites Titanium matrix based composites are of great interest especially in the automotive, aeronautical and consumer applications [1] due to their good specific modulus, high density and wear and corrosion resistance properties. Among the number of reinforcements such as SiC, TiC, Al 2 O 3 and TiB [2,3], Titanium Boride TiB is well suited for reinforcement due to the absence of intermediate phase between Ti and TiB [4][5][6], also the formation of TiB requires lesser amount of boron compared to TiB 2 . Titanium-titanium boride (Ti-TiB) composites are known for its good mechanical properties such as hardness and elastic modulus [8].…”
