Shape-Controlled TiCx Particles Fabricated by Combustion Synthesis in the Cu-Ti-C System

Abstract

TiC x particle-reinforced Cu-matrix composites were prepared in the Cu-TiC system by thermal explosion and hot press. Extracted TiC x particles with various shapes of in situ TiC x particles in the Cu-TiC system were observed through the Field Emission Scanning Electron Microscope (FESEM). It was found that octahedral and close-to-spherical, spherical or cubic TiC x could be fabricated by changing the C/Ti molar ratio and Cu content. Then, the effect of the C/Ti molar ratio and constituent element concentrations on the shape of in situ TiC x particles was determined: the shape of TiC x particles is octahedral at a C/Ti ratio of 0.4-0.6 with the presence of 70 vol% Cu; or spherical and close-to-spherical at 0.8-1.0 with the presence of 70 vol% Cu; or cubic at C/Ti ratios ≥1.0 with the presence of Cu from 80 vol%-90 vol% and even at C/Ti ratios >1.0 with the presence of 70 vol% Cu. The shape-controlled synthesis of TiC x particles in the Cu-TiC system is realized.

The Synthesis, Structure, Morphology Characterizations and Evolution Mechanisms of Nanosized Titanium Carbides and Their Further Applications

“…Particularly, distinguished by a high hardness (28~35 GPa), high specific strength, high Young’s modulus (300~480 GPa), relatively low density (4.92 g/cm 3 ), high melting point (3067~3340 °C), high thermal conductivity, and low coefficient of thermal expansion (6.4 × 10 −6 /°C), as well as good wear and corrosion resistance, titanium carbides have shown splendid prospects. [2,14,15,16,19,21,29,30,31] In the past few years, many researchers have concentrated on exploring the relationship between the physical and chemical properties of titanium carbides and their sizes, morphologies, compositions and structures, which will shed new lights on the applications in various industries [7,8,9,10,11,12,13,14,15,16,17,18,22,23,24,25,26,27,28].…”

Study on electroless Cu plating quality of in situ TiCp

“…1 b. It is widely known that the shape of reinforcing particles can have a significant impact on the properties of metal matrix materials 28 . A starkly different shape of reinforced particles can exacerbate the anisotropy of the composites, adversely affecting the quality and observations of copper plating.…”
