“…Afterwards, thermal properties such as thermal conductivity and coefficient of thermal expansion were modelled. As a result of the study, it was seen that up to 12 vol.% inclusion of B 4 C particles in the Al matrix increased the hardness of the composite material and decreased the ductility [13].…”

Within the scope of this study, the importance of boron element which has the largest reserve in Turkey and boron carbide, the most important material produced from boron, in nuclear technology has been emphasized. B4C is the basic material of control rods used to control the fission rate in nuclear reactors and is used in many nuclear reactors. The high neutron absorbing capacity of B4C material makes this material very useful. In order to examine B4C used in nuclear technology, mass attenuation coefficient (MAC) and lineer attenuation coefficient (LAC) values, which are two important radiation parameters, were examined through open access Photon Protection and Dosimetry (PSD) software which is at phy-x.net/PSD. The results obtained were compatible with the literature.

“…Currently, B 4 C/Al composites are mainly prepared by stirring casting [11], powder metallurgy [12] and infiltration techniques [13]. The infiltration method is the only approach capable of producing B 4 C/Al composites with a B 4 C content exceeding 55 vol.% [14].…”

To investigate the effect of B4C particle size on the microstructure and mechanical properties of B4C/Al composites, and to provide theoretical guidance for the subsequent thermal processing of composites, B4C/Al composites with varying B4C particle sizes (0.2 µm, 0.5 µm, 1 µm, 10 µm) were fabricated using pressureless infiltration. The microstructure of the composites was characterized using X-ray diffraction (XRD) and scanning electron microscopy (SEM), while the mechanical properties were analyzed by hardness test, three-point bending and high temperature compression. The results indicated that Al3BC and AlB2 were the primary interfacial reaction products in B4C/Al composites, and interface reaction could be alleviated with increasing particle size. B4C/Al composites with larger B4C particle sizes exhibited a relatively uniform and discrete distribution of B4C, while those with smaller B4C particle sizes showed agglomeration of B4C. The Vickers hardness and peak flow stress of B4C/Al composites gradually decreased with the increase of B4C particle size, while the bending strength, flexural modulus, and fracture toughness tended to increase. In addition, when B4C particle size was 10 µm, the composites displayed optimal comprehensive performance with the lowest peak flow stress (150 MPa) and the highest fracture toughness (12.75 MPa·m1/2).

“…5,6 Among the FGM materials, functionally graded Al matrix composites are the most preferred due to their applications in various fields like aerospace, where they are used in manufacturing aircraft fuselages and wings, engine pistons and parts, automobile drive shafts, etc, due to their excellent properties. [7][8][9] Aluminum and its alloys are generally strengthened using many reinforcements, such as Al 2 O 3 , 10 SiC, 11 B 4 C, 12 ZrO 2 , 13 NbC, 14 and VC, 15 depending on the expected property requirements.…”

Functional graded nanocomposites (FGNCs) based on Al are artificially tailored heterogeneous materials intended to serve the demand for diverse and contradicting properties used in various industrial applications. FGNCs and hybrid FGNCs (HFGNCs) based on Al reinforced with graphene and vanadium carbide (VC) were prepared using powder metallurgy techniques and investigated. Both samples were designed with a gradient composition, where the bottom layer consisted of 100% pure Al, followed by three consecutive layers containing progressively increasing amounts of reinforcement. The incorporation of graphene and VC into layer powders resulted in a decrease in both particle and crystal dimensions compared to pure Al. Adding graphene has a negative effect on bulk density samples, while VC has a positive effect. Reinforcing materials led to a decrease in thermal conductivity that reached 26.7 % for samples reinforced with VC reinforcement, except for FGNCs reinforced with graphene, which increased by ~3.3 compared to Al. The samples’ CTE and electrical conductivity values decreased, although adding graphene alone led to a slight decrease in electrical conductivity. A significant improvement in all mechanical properties was noted with additional. The HFGCNs reinforced with the largest amount of hybrid reinforcement recorded an improvement in CTE value, Young's modulus, and compressive strength by about 38.1%, 22.2%, and 20.5%, respectively, compared to Al
