“…Metallic glass (MG) particles present a promising alternative to traditional reinforcements owing to their exceptional strength and hardness. [ 24–27 ] Their metallic nature enables them to form strong interfaces with the aluminum matrix. [ 28,29 ] Additionally, they exhibit favorable Newtonian fluid behavior within their super‐cooled liquid region (between the glass transition temperature and crystallization temperature), aiding densification during the sintering process.…”

This study investigates the combined influence of Si element and reinforcing particles on the hardness and wear performance of aluminum matrix composites. The composites in focus include Fe‐based metallic glass (FMG) monolithic reinforced and FMG/SiC hybrid reinforced Al‐5 wt% Si matrix composites, fabricated through spark plasma sintering (SPS). A comprehensive investigation was carried out, encompassing the analysis of microstructural attributes and the examination of worn surfaces through field emission scanning electron microscopy. Additionally, the study scrutinized two pivotal factors—hardness and density—recognizing their pivotal roles in determining the tribological performance of these composites. The experimental findings demonstrated the presence of an oxide protective layer on the worn surfaces of all specimens. Although, FMG/SiC hybrid reinforced Al‐5 wt% Si matrix composite possessed the highest hardness value, the best tribological performance was observed in Si‐bearing monolithic reinforced composite. The addition of Si to the matrix of monolithic reinforced composite facilitated improved densification behavior and enhanced the distribution of reinforcing particles, resulting in a more stable and protective oxide layer in this specific sample. Furthermore, the study identified a transition in the operative wear mechanisms from delamination to mild abrasion and adhesion with the inclusion of Si element.This article is protected by copyright.

“…The vacuum condition can prevent or limit the oxidation and the fast heating rate along spark and plasma condition can restrict coarse growth of formation phases and crystal grains. [23][24][25][26][27] This study investigated anisotropic tensile behavior of CNT reinforced Al matrix composites fabricated by dry ball milling, SPS and post-SPS repeated hot rolling, which were related to microstructures including dispersibility of CNT and material defects such as voids and cracks in the composites. The microstructures were observed using a scanning electron microscope (SEM) and transmission electron microscope (TEM).…”

This study aims to strengthen carbon nanotube (CNT)/Al composites, which were fabricated by a combination of spark plasma sintering (SPS) and repeated hot rolling techniques. Dry ball milling was conducted to uniformly disperse CNT in Al powders. The microstructures of the CNT/Al composites including dispersibility of CNT were observed using a scanning electron microscope (SEM) and transmission electron microscope (TEM). Ball milling treatments promoted to reduce the number of CNT aggregations and increase C concentrations in the CNT aggregations in the composites. Anisotropic tensile behavior was also investigated, which demonstrated that the post-SPS repeated hot rolling can highly enhance the tensile strength as well as deformability of the composites.
