Regulating Mechanical Properties of Al/SiC by Utilizing Different Ball Milling Speeds

Abstract

Advanced materials with high strength are in great demand for structural applications, such as in aerospace. It has been proved that fabrication strategy plays a vital role in producing composites to satisfy these needs. This study explores new strategies for flake powder metallurgy, with the aim of designing an effective strategy to achieve the highest possible mechanical strength for a metal matrix nanocomposite without changing the reinforcement fraction. Different strategies were used to regulate the mechanical properties for similar composites based on shift speed ball milling. Ultra-ductile composites on one hand, and ultra-strong composites on the other hand, were fabricated using similar composites. The results demonstrate that shifting the ball milling speed can be used to manipulate the mechanical properties of the composite to achieve the desired properties for any specific application.

Fabrication and Characterization of Cu/SiC‐Based Axially Functionally Graded Beam

“…for 8 h, provided the machine cools for 10 min at each 1 h interval. [ 23 ] After the ball milling of pure Cu powder, it was sieved and the fine particles were separated. Then, the sieved Cu powder (50−37 μm) was mixed with initial SiC powder in the metal−ceramic wt% ratios of 90/10 and 80/20.…”

Research progress on ceramic nanomaterials reinforced aluminum matrix nanocomposites

“…Afterwards, samples were hot extruded at extrusion ration of 16:1 under the flow of argon gas [73]. Microstructure and properties of metal matrix nanocomposites were influenced by process parameters in powder metallurgy method [74]. Salur et al [75] reported influence of milling time on microstructure of Y 2 O 3 nanoparticle reinforced aluminium matrix composite.…”

“…As compared with base alloy materials, compressive strength and micro hardness of the hybrid nanocomposite has been improved 26.5 and 40%, respectively [102]. Better load carrying properties of the nanocomposite materials was due to the decrease in grain structure, uniform dispersion and distribution of nanomaterials, and formation of dislocation because of the thermal mismatch between aluminium and ceramic nanoparticles [74]. Mechanical and wear properties of alumina and graphene oxide incorporated aluminium matrix hybrid nanocomposites has been described by Mohammed et al [103].…”

Electrochemical Behavior of Inductively Sintered Al/TiO2 Nanocomposites Reinforced by Electrospun Ceramic Nanofibers

“…A high-frequency induction-heated sintering (HFIHS) process is one of the most effective consolidation techniques in which simultaneous pressure and temperature are applied to the powder mixture sample in a vacuumed atmosphere within a very short time to produce a high-density and homogeneous composite [29,30]. This advanced sintering process is beneficial because its densification ability is very good, which produces high-density samples with convergent real and theoretical densities, i.e., relative density is very close to 100% [31].…”
