The Influence of ScF3 Nanoparticles on the Physical and Mechanical Properties of New Metal Matrix Composites Based on A356 Aluminum Alloy

Inconel 625/TiB2 Metal Matrix Composites by Direct Laser Deposition

“…However, the introduction of ceramic particles into the metal matrix in order to obtain MMCs entails a series of technological problems. In classical metallurgy processes, these problems are associated with poor wetting of ceramic particles with liquid metal, uneven distribution of particles within the metal matrix, and particle flotation, among others [24][25][26].…”

The Impact of Particle Reinforcement with Al2O3, TiB2, and TiC and Severe Plastic Deformation Treatment on the Combination of Strength and Electrical Conductivity of Pure Aluminum

“…The SPD process also amplifies the particle reinforcement effect by the even redistribution of titanium diboride particles in aluminum grains, thus activating the Orowan mechanism. As such, the particles become an obstacle for the travel of dislocations [15]. The fact that Microhardness tends to increase both after the introduction of hard-melting particles and after increasing the number of treatment cycles.…”

“…The SPD process also amplifies the particle reinforcement effect by the even re-distribution of titanium diboride particles in aluminum grains, thus activating the Orowan mechanism. As such, the particles become an obstacle for the travel of dislocations [15]. The fact that the presence of titanium diboride particles are not causing a substantial reduction of the electrical conductivity in the structure of aluminum is explained by the fact that the distance between TiB 2 particles is greater or equal to the distance of the free pass of electrons.…”

“…This, in turn, improves mechanical properties in accordance with the Hall-Petch relationship. Also, the strengthening is achieved via the Orowan mechanism since ceramic particles are an obstacle to the travel of dislocations [15]. The mechanical properties of the aluminum composites are rather fully studied in References [12][13][14][15][16].…”

Investigation of structure, mechanical properties and crystallization of aluminum alloys containing aluminum oxide nanoparticles

“…In this case, composite material properties will be determined by the type and amount of the particles introduced. The results obtained [9][10][11][12][13][14] allow us to assert that MMNCs based on aluminum and with nanoparticles introduced into them have higher performance characteristics, in particular, ultimate strength, yield strength, plasticity, hardness, heat resistance, etc. [15][16][17][18].…”
