“…In the last two decades, cellular materials have experienced a continuous spread in all top industries. Whether it is materials with a metallic [1,2], polymeric [3,4], or ceramic [5] matrix, this use is due to the high characteristics they develop. In this sense, among the most significant properties of cellular materials are low weight, high strength, stiffness, high-energy absorption capacities, good thermal and sound insulation, as well as good vibration damping [6][7][8].…”

Currently, the automotive industry is looking for their new products to have a density as low as possible so that CO2 emissions decrease. Metallic foams have attracted a great deal of interest in this industry because of their multiple advantages. They can be produced at a relatively low cost and have advantageous properties, especially due to their ability to absorb energy. In the framework of this study, 42 specimens were tested to determine the impact energy and Charpy impact strength according to the cutting orientation. Before being notched according to the ISO 148 standard, their specific mass was determined. For the tests, an Instron CEAST 9050 Charpy test machine was used. The impact strength was determined according to the cutting orientation, and the results obtained by the mass density groups were compared. It could be observed that the cutting orientation of the specimens does not have a clear influence on the impact strength; this is due to the irregular shape of the closed cell, however, the grouping of the specimens on specific density samples has influenced the impact strength.

“…However, Al is the most preferred material because it is easily castable, has high corrosion resistance and can be heat-treatable (Yavuz et al ., 2023). Considering fillers, ceramic-based granules (Al 2 O 3 , SiC and SiO 2 ) are noticed from micron to millimetric scales (Maróti and Orbulov, 2023). Additionally, micro-scale glass balloons and hollow glass spheres are also utilized (Anbuchezhiyan et al ., 2017).…”

PurposeThis study aims to elucidate the machining properties of low-cost expanded clay-reinforced syntactic foams by using different neural network models for the first time in the literature. The main goal of this endeavor is to create a casting machining-neural network modeling flow-line for real-time foam manufacturing in the industry.Design/methodology/approachSamples were manufactured via an industry-based die-casting technology. For the slot milling tests performed with different cutting speeds, depth of cut and lubrication conditions, a 3-axis computer numerical control (CNC) machine was used and the force data were collected through a digital dynamometer. These signals were used as input parameters in neural network modelings.FindingsAmong the algorithms, the scaled-conjugated-gradient (SCG) methodology was the weakest average results, whereas the Levenberg–Marquard (LM) approach was highly successful in foreseeing the cutting forces. As for the input variables, an increase in the depth of cut entailed the cutting forces, and this circumstance was more obvious at the higher cutting speeds.Research limitations/implicationsThe effect of milling parameters on the cutting forces of low-cost clay-filled metallic syntactics was examined, and the correct detection of these impacts is considerably prominent in this paper. On the other side, tool life and wear analyses can be studied in future investigations.Practical implicationsIt was indicated that the milling forces of the clay-added AA7075 syntactic foams, depending on the cutting parameters, can be anticipated through artificial neural network modeling.Social implicationsIt is hoped that analyzing the influence of the cutting parameters using neural network models on the slot milling forces of metallic syntactic foams (MSFs) will be notably useful for research and development (R&D) researchers and design engineers.Originality/valueThis work is the first investigation that focuses on the estimation of slot milling forces of the expanded clay-added AA7075 syntactic foams by using different artificial neural network modeling approaches.

Aluminum smelter waste (ASW) is a big contributor to landfill and its recycling has been of great interest. This study characterizes the ASW powder, manufactures aluminum matrix syntactic foams using ASW, and investigates their mechanical properties. Different particle size groups of the ASW powder contain different impurities and porosities, leading to different strengths. The mechanical behaviors of the ASW syntactic foams are similar to existing metal matrix syntactic foams. The compressive yield strength, plateau strength, and specific energy absorbed vary in the ranges of 111–398, 33–145 MPa, and 18–71 MJ m−3. The flexural strength and flexural modulus vary in the ranges of 8–138 MPa and 13–72 GPa. The peak impact strength and impact energy in drop‐weight impact vary in the ranges of 192–547 MPa and 16–29 J. Particle size and heat treatment of the ASW powder have significant effects on the properties and brittleness of the resultant syntactic foam.
