“…The wear resistance of these alloys can be improved considerably by adding ceramic reinforcements into aluminium, leading to the formation of the metal-matrix composites (MMCs). Incorporation of ceramic reinforcements can result in a favourable combination of the high ductility and the high strength [2,3]. The ceramic reinforcements generally can be in the form of particles, whiskers and fibres.…”

“…On the other hand, the microscopic nonuniformity of the particle distribution, created by dendrite structure formation and usually in the form of clustering, is considered as the reason for internal stresses and also stress triaxiality, which are responsible not only for the special hardening behavior, but also for the early appearance of particle cracking, particle interface debonding, and void formation in the matrix [30][31][32].…”

In the present study, attempts were made to coat the B4C powders with TiB2 via a sol-gel process, and then squeeze cast A356 matrix composites reinforced with coated B4C particles were fabricated. X-ray diffraction studies also confirmed the existence of boron carbide and some other reaction products such as TiB2, AlB2 and Al3BC in composite samples. It was observed that the amount of porosity increased with increasing the volume fraction of composites. Tensile behavior and hardness of unreinforced alloy and composites were evaluated. It was noted that the elastic constant, strain-hardening and UTS of the metal matrix composites (MMCs) were higher than those of the un-reinforced Al alloy and increased with increasing of coated B4C content. The strengthening of particulate reinforced metal-matrix composites is associated with a high dislocation density in the matrix due to the difference in coefficient of thermal expansion between the reinforcement and the matrix.

“…The yield strength and UTS of the materials were found to increase with increasing of B 4 C content. The great enhancement in values observed in these composites in comparison to monolithic aluminum is due to grain refinement, the strong multidirectional thermal stress at the Al/B 4 C interface, small particle size and good distribution of the B 4 C particles and low degree of porosity which leads to effective transfer of applied tensile load to the uniformly distributed strong B 4 C particulates (Needleman and Suresh, 1989;Suresh et al, 2003;Reddy, 2003). It is assumed that the non-linear part of the true stress-true strain curves followed Zener-Hollomon relationship (Kashyap et al, 2000):…”

In this research, the mechanical properties of A356 matrix reinforced with B 4 C particulates were first experimentally investigated and then a combination of artificial neural network (ANN) and finite element technique was implemented in order to model the mechanical properties including yield stress, UTS, hardness and elongation percentage. Microstructural characterization revealed that the B 4 C particles were distributed between the dendrite branches. The strain-hardening behavior and elongation to fracture of the composite materials appeared very different from that of un-reinforced Al alloy. It was noted that the elastic constant, strain hardening and UTS of the MMCs is higher than that of the un-reinforced Al alloy and increase with increasing of B 4 C content. It is also revealed that predictions of ANN are consistent with experimental measurements for A356 composite and considerable savings in terms of cost and time could be obtained by using neural network model. The results of this research were used for solidification codes of SUT CAST software.
