Detailed Micromeritics and Rheological Study of Mild Steel Grinding Chips: A Sustainable Feedstock for Additive Manufacturing | Journal of Materials Engineering and Performance

Popis výsledku v původním jazyce

The present article explores the sustainable recyclability of mild steel grinding chips (MSGCs) produced by a high-speed cut-off saw (Make: KPT Industries Ltd. Jaysinghpur Maharashtra, India) as feedstock for additive manufacturing (AM). The morphological, elemental and crystallographic analysis was exhibited by scanning electron microscope (SEM), energy dispersive spectroscopy (EDS) and x-ray diffraction (XRD), respectively. Further, the particle size distribution of MSGCs was evaluated using an optical particle size analyzer. The appearance of the MSGCs in SEM micrographs resembled the metal powders produced by atomization; however, the EDS and XRD results revealed the formation of Fe&lt;inf&gt;3&lt;/inf&gt;O&lt;inf&gt;4&lt;/inf&gt; and the presence of iron, carbon and manganese as the main constituents of mild steel. The particle size distribution belongs to a broader range of 34-240 µm and bears a span of 1.6 with an average particle size of 132 µm. The preliminary rheological analysis of MSGCs was carried out using the Hausner ratio, Carr’s index and angle of repose; their values of 1.27, 21 and 44.30°, respectively, exhibited moderate flowability. Further, the Freeman FT4 rheometer was used to critically analyze inter-particle friction, particle-to-wall friction and compressibility of the MSGCs. The linear internal friction angle was found as 39.9°, whereas the effective internal friction angle was found as 41.6°. The value of the flow function 12.9 and the average value of the wall friction angle 11.5° rendered the MSGCs as free-flowing particles. The morphological, elemental and rheological analysis tends to conceive that the MSGCs may be an alternate and sustainable feedstock for AM.
