“…However, a noticeable increase in the impact strength value along with the increase in temperature may indicate an increase in matrix's role in load transfer. A similar relationship was observed in the work of [17] on composites produced on the basis of 6061 alloy with 20% Al2O3 content and in the work [18] on the basis of 5083 Al alloy reinforced with the SiC particles.…”

“…These materials are characterized by the high mechanical properties such as tensile, bending or compression strength, but on the other hand they are not characterized by the large impact strength. These issues have been investigated by researchers using composite materials with different matrices and with various contents of the reinforcing elements [14][15][16][17][18]. Relatively few, however, can be found in literature on impact strengths of metallic composite materials at elevated temperatures, which may be essential during their use.…”

The paper presents the results of research of impact strength of aluminum alloy EN AC-44200 based composite materials reinforced with alumina particles. The research was carried out applying the materials produced by the pressure infiltration method of ceramic preforms made of Al2O3 particles of 3-6m with the liquid EN AC-44200 Al alloy. The research was aimed at determining the composite resistance to dynamic loads, taking into account the volume of reinforcing particles (from 10 to 40% by volume) at an ambient of 23°C and at elevated temperatures to a maximum of 300°C. The results of this study were referred to the unreinforced matrix EN AC-44200 and to its hardness and tensile strength. Based on microscopic studies, an analysis and description of crack mechanics of the tested materials were performed. Structural analysis of a fracture surface, material structures under the crack surfaces of the matrix and cracking of the reinforcing particles were performed.

“…In this sense, it could be possible to improve the damage tolerance of metallic structures by modifying conventional-design configurations to take maximum profit from the strong points of aluminum alloys and de-emphasize their weaker points. [4][5][6] Laminated metal composites consist of alternating metal or reinforced metal layers that are bonded with ''sharp'' interfaces. Laminated metal composites can dramatically improve many properties, including toughness, fatigue behavior, impact behavior, wear, corrosion, and damping capacity; or provide enhanced formability or ductility.…”

The microstructure and the mechanical properties of a multilayer composite laminate based on aluminum 7075 and 2024 alloys produced by hot roll bonding were examined. The composite laminate has been tested at room temperature under Charpy-impact tests, three-point bend tests, and shear tests on the interfaces. The toughness of the post-rolling tempered and T6-treated composite laminate, measured by impact-absorbed energy in the crack-arrester orientation, was more than 20 times higher than that of the monolithic Al 7075 alloy and 7 times higher than that of Al 2024 alloy. The outstanding toughness increase of the composite laminate in the post-rolling tempered and T6-treated condition is mainly due to the mechanism of ''interface predelamination.'' By this fracture mechanism, the interfaces are debonded before the main crack reaches them, warranting delamination in all interfaces. Therefore, delamination and crack renucleation in every layer are responsible for the improvement in toughness.

“…1 Particle reinforced aluminum matrix composites (AMCs), because of its low density, high strength, low coefficient of thermal expansion, and outstanding abrasion resistance, can well meet these requirements and, accordingly, have been widely used in the industrial fields of aerospace, automotive, microelectronics, etc. [2][3][4] As the potentially feasible reinforcement for AMCs, TiC exhibits a number of favorable characteristics, such as high elastic modulus, high hardness, and especially its good wettability and thermodynamic stability within the molten aluminum. 5 Normally, the large sized reinforcing particles are used in the conventional processing of TiC particle reinforced AMCs, ranging from several tens of micrometers to hundreds of micrometers.…”

Selective laser melting (SLM), due to its unique additive manufacturing processing philosophy, demonstrates a high potential in producing bulk-form nanocomposites with novel nanostructures and enhanced properties. In this study, the nanoscale TiC particle reinforced AlSi10Mg nanocomposite parts were produced by SLM process. The influence of “laser energy per unit length” (LEPUL) on densification behavior, microstructural evolution, and wear property of SLM-processed nanocomposites was studied. It showed that using an insufficient LEPUL of 250 J/m lowered the SLM densification due to the balling effect and the formation of residual pores. The highest densification level (>98% theoretical density) was achieved for SLM-processed parts processed at the LEPUL of 700 J/m. The TiC reinforcement in SLM-processed parts experienced a structural change from the standard nanoscale particle morphology (the average size 75–92 nm) to the relatively coarsened submicron structure (the mean particle size 161 nm) as the applied LEPUL increased. The nanostructured TiC reinforcement was generally maintained within a wide range of LEPUL from 250 to 700 J/m and the dispersion state of nanoscale TiC reinforcement was homogenized with increasing LEPUL. The sufficiently high densification rate combined with the uniform distribution of nanoscale TiC reinforcement throughout the matrix led to the considerably low coefficient of friction of 0.38 and wear rate of 2.76 × 10−5 mm3 N−1 m−1 for SLM-processed nanocomposites at 700 J/m. Both the insufficient SLM densification response at a relatively low LEPUL of 250 J/m and the disappearance of nanoscale reinforcement at a high LEPUL of 1000 J/m lowered the wear performance of SLM-processed nanocomposite parts.
