LetterNanometric Si3N4 particulate-reinforced aluminum composite
Abstract
The nanometric Si3N4 particulate-reinforced aluminum composite was fabricated by a powder metallurgy technique. The tensile properties of the composite were tested, and the polished composite and the tensile fracture surface were observed. The 1vol.%Si3N4 (15 nm)/Al composite exhibited a strength comparable to that of the 15vol.%SiCp (3.5 μm)/Al composite.

In this study, porthole die extrusion was first performed on a 0.5 wt% GNP-nanoplatelet-reinforced aluminium matrix composite by using welding chambers having heights of 10, 15, and 20 mm. The effects of the welding chamber height on the microstructure and mechanical properties of the composite in the welding zone were studied. The observation results show that there are no macroscopic defects in the interface of the extrudate by the die with different welding chamber heights. The welding degree and ductility of the longitudinal weld of the extrudate increase with the increase of the height of the welding chamber. When the welding chamber height was 20 mm, the comprehensive mechanical properties of the composite along the extrusion direction and the vertical direction were the best. This was mainly because a higher hydrostatic pressure and shear force in the welding chamber with the height of 20 mm increased the recrystallisation degree of the composite, resulting in smaller sizes and an even distribution of the GNP and alumina nanoparticles inside the grain, which played positive role in hindering the dislocation slip. Further, the interface strength between GNP and the matrix was also enhanced characterized by the light and sharp tearing edge in the tensile fractography. The presence of GNP hindered the closure of micro-holes in the weld, and an increase in the welding chamber height effectively reduced the size of micro-holes, thereby improving the welding quality. So larger welding chamber height should be recommended without sacrificing stability and life of the die.
Pulse-reverse electrodeposition of Ni-Co/graphene composite films with high hardness and electrochemical behaviour
2023, Diamond and Related MaterialsThis study reports the production of functional Ni-Co/graphene coating obtained by pulse-reverse current (PRC) electrodeposition method in Ni-Co plating bath containing graphene (Gr) to be co-deposited. Effects of graphene concentration on the morphology, microstructure, microhardness, and electrochemical behaviour of the resulting Ni-Co/graphene thin film were investigated. It was found that Gr introduced into the electrolyte and its concentration affected the composition as well as the structure of the composite coatings. A higher Gr concentration in the electroplating bath led to a higher Co concentration in Ni-Co alloy coatings. Ni-Co alloys and Ni-Co/Gr composite coatings exhibited a compact surface under PRC current, an average crystallite size in the range of 8–10 nm, and a solid solution structure of Ni (Co). The electrochemical behaviour of the composite coating improved with increasing Gr content, but decreased with higher Gr concentration (0.8 g/l). Ni-Co/Gr nanocomposite coating also exhibited a higher microhardness of 610 HV than monolithic Ni-Co coating of 458 HV.
Failure of Metal-Matrix Composites
2023, Comprehensive Structural IntegrityThe microstructures and mechanical properties of a 5vol%SiC/AA2024 nanocomposite fabricated by powder metallurgy
2021, Materials CharacterizationA 5vol%SiC/AA2024 nanocomposite was prepared by a powder metallurgy routine involving high energy ball milling (HEBM), spark plasma sintering (SPS) and hot extrusion. The microstructures and mechanical properties of the 5vol%SiC/AA2024 nanocomposite samples prepared using different HEBM and SPS times were investigated in detail. It was found that increasing the milling time from 12 to 24 h caused refinement of Al grains and better dispersion of SiC nanoparticles, leading to a significantly increase of hardness and strength. Increasing the SPS time from 5 to 10 min helped to improve the quality of interparticle bonding, and resulted in grain growth and consequently the formation of a bimodal microstructure which is beneficial for the improvement of ductility. Optimized tensile mechanical properties were achieved in a 5vol%SiC/AA2024 nanocomposite with ball milling time of 24 h and SPS time of 10 min, with its yield strength, ultimate tensile strength and elongation to fracture being 463 MPa, 626 MPa and 4.4%, respectively. Based on the analysis of the contributions of different strengthening mechanisms to the strength, nanoparticle strengthening and grain boundary strengthening made the majority of the contributions to the improved strength of the 5vol%SiC/AA2024 nanocomposite.
High as-cast strength die-cast AlSi9Cu2Mg alloy prepared by nanoparticle strengthening with industrially acceptable ductility
2021, Journal of Alloys and CompoundsHigh as-cast strength die-cast AlSi9Cu2Mg alloy was achieved with industrially acceptable ductility, via the addition of titanium diboride nanoparticles. The main intermetallic compounds in the die-cast AlSi9Cu2Mg alloy were identified as θ–Al2Cu and Q–Al5Cu2Mg8Si6 phases. The Fe-rich compound formed in the present die-cast alloy with a high Mn/Fe ratio of 3:1 was determined as the BCC structured α–Al15(Fe,Mn)3Si2 phase with a lattice parameter of a = 1.2702 nm, and the Fe-rich compound had highly faceted morphology with {110} surface termination. The Al matrix phase in the die-cast AlSi9Cu2Mg alloy was refined by ∼65% from 18.1 μm to 6.4 μm, after adding 3.0 wt% titanium diboride nanoparticles. The titanium diboride nanoparticles in the alloy showed coherent interface with the Al matrix, with the (11-1) lattice face of Al parallel to the (0001) lattice face of titanium diboride. The as-cast AlSi9Cu2Mg alloy containing 3.0 wt% titanium diboride nanoparticles exhibited the high yield strength of 233 ± 3 MPa and the tensile strength of 398 ± 7 MPa, as well as the industrially acceptable elongation of 4.8 ± 0.7%, and it showed at least 23% improvement in the as-cast yield strength over the existing die-cast Al alloys. The strengthening by nanoparticle and coherent interface (∼32 MPa) was higher than that by the refining of Al matrix (∼10 MPa). The addition of titanium diboride nanoparticles also affected the fracture of the die-cast AlSi9Cu2Mg alloy, and cracks were prone to form in the Q and Fe-rich compounds, after the addition of titanium diboride nanoparticles.
Tensile Response of Al-Based Nanocomposites
2021, Encyclopedia of Materials: CompositesIn recent years, aluminum matrix nanocomposites have gained increased importance compared to conventional aluminum-based alloys owing to their better mechanical, thermal, and tribological properties. High tensile strength properties are considered to be an important criterion in the selection of materials for automotive, aerospace, military, and other lightweight applications. The tensile properties of the aluminum-based nanocomposite are governed by several factors including the type of processing technology, amount of reinforcement, microstructural features, and so on. Accordingly, this article discusses the recent advancements in the fabrication of aluminum matrix nanocomposites with low volume addition of ceramics nanoparticles. Firstly, the importance of the powder metallurgy technique on the synthesis of aluminum matrix nanocomposites is discussed. Thereafter, the influence of microstructural influences of the nanoparticles on the tensile properties of the aluminum matrix composite system is outlined. Strengthening mechanisms responsible for the enhancement in the tensile yield strength properties are also discussed. The relationship between the hardness and tensile strength properties of the nanocomposites is established. The tensile strength properties of different Al matrix nanocomposites relationship is summarized. Finally, a comparison is made between the recently reported Al matrix nanocomposites systems to gain insight on the effect of hardness and particle size on the tensile strength properties.
