This study investigates the fabrication, wear characterization, and coefficient of friction (COF) prediction open-cell AlSn6Cu–Al2O3 composites obtained by a liquid-state processing technique. Focusing on behavior under varying loads using pin-on-disk method, this research characterizes microstructure phase composition via SEM, EDS, XRD analyses. A novel aspect is application an LSTM recurrent neural network model for fast accurate COF composites, eliminating need extensive experimental...
Aluminum and A356 alloy foam castings are produced using a melt-foaming method. Prior to foaming, the melt is modified with nano-sized particles (SiC, TiN, or Al2O3). The mixed micro-sized Al particles, which ultrasonically treated hot-extruded. Thus, so-called “modifying nano-composition” obtained. resulting compositions introduced into of at following mass concentrations nanoparticles: SiC: 0.038 wt. %; TiN: 0.045 Al2O3: 0.046 %. For foam, we use concentrations: 0.039 0.052 0.086...
Cylindrical foam castings of Al and A356 alloy were produced using a melt foaming method with the introduction Ca TiH2. Foam crystallization takes place in cooled thin-walled metal mold. Samples cut off from are investigated by X-ray tomography, quantitative data for porosity, average pores diameter cells wall thickness obtained. It is found that porosity mainly open. Same samples tested quasi-static mode compressive strength determined. The influence on analyzed.
This data article describes the stress-strain curves, energy absorption and efficiency of open-cell AlSi10Mg materials AlSi10Mg-SiC composites with different pore sizes strain rates. The were obtained by quasi-static compression loading up to 60% at rates 0.01 0.001 s-1 according ISO 13,314:2011 standard. can be used compare effects size rate on compressive properties materials. are related research entitled "Fabrication, Experimental Investigation Prediction Wear Behavior Open-Cell...
