“…To overcome these challenges, various hard particles such as W [8], SiC [9][10][11][12][13] and TiB [14][15][16][17] were used as reinforcement to increase the wear resistance and hardness of Ti and Ti64. C and TiB 2 particles have been used to obtain a reinforced architecture with increased tensile strength [18][19][20][21].…”

Ceramic particle reinforcement can be used to improve the surface properties of Ti6Al4V (Ti64) alloy. Powder metallurgy route is a promising method to fabricate such reinforced Ti64 components. To assess the relevance of this technique, this work investigates the effect generated by the addition of TiN particles in Ti64 powder during free sintering. TiN reinforcement particles were randomly distributed in the Ti64 matrix with three different concentrations in two configurations: completely reinforced and unreinforced-reinforced bilayer. Dilatometry was used to obtain the shrinkage kinetics of samples at 1200, 1300 and 1400°C under inert atmosphere and to investigate the impact of reinforced particles on the sintering behaviour. The microstructure of sintered materials was shown to be lamellar in the unreinforced material and equiaxed in reinforced materials. Finally, the Vickers microhardness measurement showed the huge benefit of adding TiN particles to increase the mechanical strength of the Ti64 alloy.

“…Moreover, composites are reinforced with different types of reinforcements, such as continuous, long, and short fibers and particles [ 19 , 20 , 21 , 22 ]. In this regard, research achievements show that reinforced TMCs with whiskers or particles have more isotropic behaviors than reinforced ones with continuous fibers [ 23 , 24 , 25 , 26 , 27 ]. However, the whiskers of titanium monobromide (TiB) and the particles of titanium carbide (TiC) that can be obtained via high-temperature reactions [ 28 ] exhibit a high modulus, a relative chemical stability, a high thermal stability, and clean interfaces while retaining the same density and thermal expansion coefficient as TMCs [ 29 , 30 , 31 ].…”

A Novel Approach for Analyzing the Effects of Almen Intensity on the Residual Stress and Hardness of Shot-Peened (TiB + TiC)/Ti–6Al–4V Composite: Deep Learning

In the present study, the experimental data of a shot-peened (TiB + TiC)/Ti–6Al–4V composite with two volume fractions of 5 and 8% for TiB + TiC reinforcements were used to develop a neural network based on the deep learning technique. In this regard, the distributions of hardness and residual stresses through the depth of the materials as the properties affected by shot peening (SP) treatment were modeled via the deep neural network. The values of the TiB + TiC content, Almen intensity, and depth from the surface were considered as the inputs, and the corresponding measured values of the residual stresses and hardness were regarded as the outputs. In addition, the surface coverage parameter was assumed to be constant in all samples, and only changes in the Almen intensity were considered as the SP process parameter. Using the presented deep neural network (DNN) model, the distributions of hardness and residual stress from the top surface to the core material were continuously evaluated for different combinations of input parameters, including the Almen intensity of the SP process and the volume fractions of the composite reinforcements.

“…In order to employ continuous reinforced metal matrix composites (MMCs) by means of powder metallurgy, it is essential to be able to control the placing of the reinforcement in the matrix. By using slurry 20,21 or a continuous titanium powder pre-deposition technique on silicon carbide (SiC) filaments that have been positioned before being sintered, 22,23 MMCs can be produced. However, as the diameter of the carbon filaments is more than 10 times smaller than that of the SiC filaments, this process proves to be unsuitable for obtaining sufficient fibre volume fraction.…”

An alternative route for producing aluminium matrix reinforced with continuous carbon fibres is proposed in this paper. On the one hand, liquid aluminium does not wet carbon; on the other hand, however, the two form a reactive system leading to carbide formation. A novel way to obtain continuous carbon fibre-reinforced aluminium was investigated, using spark plasma sintering with aluminium foils as raw material. Sintering parameters were adjusted to achieve the effective welding of aluminium foils and penetration of the metal between the filaments. A quality assessment of the fibre/aluminium coupling is presented. Interfaces were then investigated by scanning electron microscopy, transmission electron microscopy and energy-dispersive ray spectroscopy. An effective cohesion of fibres with the matrix was shown. The manageable fibre positioning could result in unidirectional architecture and reinforcement rate should be handled through foil thickness and yarn properties. Using tensile tests, cohesion between aluminium and carbon fibres can be quantified.
