“…Adeosun et al 20 studied the effect of EAFD addition in 2-20 wt.% content, on the mechanical properties of 6063 aluminum alloy, by casting in a sand mould, which was subsequently cold rolled and heat treated. Flores-Vélez et al 28 produced a AMC based on the conventional powder metallurgy technique and obtained the best results of compressive strength and hardness for samples made with 10 wt.% EAFD to about 70 HV. Selvam et al 29 applied fly ash in AA6061 aluminum alloy composites obtaining maximum value of 116 HV to 12 wt.% of waste.…”

“…Selvam et al 29 applied fly ash in AA6061 aluminum alloy composites obtaining maximum value of 116 HV to 12 wt.% of waste. Other wastes have been applied as reinforcement aluminum composite, such as granulated slag 28 , red mud 30 , rice husk ash and graphite 31 . In addition, in the present work it was revealed that EAFD levels higher than 5% may cause fracture of the composite during the sintering.…”

Eletric arc furnace dust is dangerous solid waste that is generated in steel manufacturing processes. The utilization of the dust from these industries avoids disposing it into industrial waste landfills and saves costs. In this study, an attempt has been made to fabricate aluminum matrix composites reinforced with EAFD particulate, throught the conventional powder metallurgy technique. Al-5%EAFD proposed was then compared to the AA7075 alloy, manufactured under the same conditions. According to the results obtained, the addition of EAFD into aluminum matrix resulted in increased microhardness values and had significant contributuion to improve Storage modulus compared with the base metal. The reinforcement particle was uniformly dispersed into the matrix and intermetallic phases were not observed in the content of waste blended into the composite.

“…Moreover, EAFD is classified as hazardous by several agencies, including the Brazilian Association of Technical Standards [ 4 ], the Environmental Protection Agency [ 5 ], and the European Waste Catalog [ 6 ], due to its content of metals such as zinc, cobalt, copper, lead, and cadmium. Therefore, despite it being considered a renewable resource [ 7 ] and a secondary raw material [ 8 ], finding a suitable use for the EAFD represents a strong challenge, and some studies have reported recycling it as filler in composite materials with polymer [ 9 , 10 ], ceramic [ 11 ], cement [ 12 ], concrete [ 7 ], and metal matrix [ 13 , 14 , 15 ]. Regarding the latter, aluminum matrix composites (AMCs) in particular are of great interest because alloys such as the 7075 aluminum alloy (AA7075) exhibit characteristics (low density, high strength-to-weight ratio) that are of great importance, including for applications in the automotive, aeronautics, and naval industries.…”

Electric Arc Furnace Dust Recycled in 7075 Aluminum Alloy Composites Fabricated by Spark Plasma Sintering (SPS)

The reuse of industrial waste, such as electric arc furnace dust (EAFD) as reinforcement in aluminum matrix composites (AMC), is still little explored even though it has shown potential to improve the mechanical properties, such as hardness and mechanical strength, of AMCs. To propose a new alternative for EAFD recycling, AA7075-EAFD composites were produced by spark plasma sintering (SPS). The starting powders were prepared by high-energy milling with different weight fractions of EAFD in two particle size ranges added to an AA7075 matrix. SEM shows that the distribution of reinforcement particles in the matrix is homogeneous with no agglomeration of the particles. XRD patterns of initial powders and the SPS-sintered (SPSed) samples suggest that there was no reaction during sintering (no additional peaks were detected). The relative density of all SPSed samples exceeded 96.5%. The Vickers microhardness of the composites tended to increase with increasing EAFD content, increasing from 108 HV (AA7075 without reinforcement) up to 168 HV (56% increase). The maximum microhardness value was obtained when using 15 wt.% EAFD with a particle size smaller than 53 μm (called G1), showing that EAFD presents a promising potential to be applied as reinforcement in AA7075 matrix composites.

“…The idea is becoming popular and several studies have been done with fly-ash, glass, and other by-products. [1,2] Slag is one of the major waste products of steelmaking production, regularly generated each year in significant volumes as thousands of tons. This by-product has the potential for added value if a diversity of suitable end products could be produced from these materials.…”

The present work provides results of aluminum metal matrix composites reinforced with granulated slag (GS). The study concerns the synthesis and properties of Al/GS composites based on powder metallurgy techniques. Dilatometry, differential thermal analysis, and scanning electron microscopy were employed to track the reactions between the aluminum matrix and the granulated slag during the sintering treatment. Thermal analysis results revealed an exothermic reaction at 640°C, leading to the formation of the intermetallic compound Al 3 Fe. The hardness and compressive strength of the sintering compacts were determined as a function of the GS content. The best results were achieved with the aluminum composites with 15 wt.% GS, reaching compressive strengths up to 372 MPa.
