Abstract:
In this article, the features of the in-situ synthesis, microstructure evolution and mechanical properties of TiC-Cu composites obtained by mechanical milling and spark plasma sintering (SPS) are presented. The goal of this work is to study the effect of the carbon source on the microstructure evolution during the manufacturing of TiC-Cu composites from Ti-C-3Cu mixtures. Graphite, nanodiamonds and carbon black powders are compared as the carbon sources in the synthesis in terms of their influence on the structural evolution of the composite mixtures. In the case of graphite, mixing and alloying are retarded at the initial stages of milling. The use of carbon black and nanodiamonds ensures faster conversion of the reactants into the products during milling compared with graphite, as concluded from the studies of thermal explosion of those mixtures. Irrespective of the source of carbon, melting is observed at the contacts between equiaxed particles in the materials consolidated by SPS leading to the formation of composites with an interesting (unconventional) microstructure. The compressive yield strength, ultimate compressive strength and hardness of selected TiC-Cu composites are reported. A TiC-Cu composite with an attractive combination of properties has been obtained (processing conditions: Ti-Cgraphite-3Cu mixture, 10 min of milling, SPS at 980°C): a relative density of 95%, a compressive yield strength of 820 MPa, an ultimate compressive strength of 920 MPa, a hardness of 360 HV, a deformation at fracture of 2%, and an electrical conductivity of 18% of the International Annealed Copper Standard.
