In this work, structural, microstructural, thermal, and magnetic properties of a Fe25at%Al alloy produced by highenergy mechanical milling were investigated by Xray diffraction (XRD), scanning electron microscopy (SEM), differential scanning calorimetry (DSC), and vibrating sample magnetometry (VSM) techniques.
احصل على السعر2 Then ballmilling was carried out from 1 to 48 hours under the rotation speed of 500 rpm in a solventfree condition. We denote the ballmilled samples as BACx, where x refers to the ballmilling time. The. Results and discussion. Surface area and porous structure are the most important structural characters of activated carbon.

احصل على السعرThe results showed that the feed particle size had a significant influence on the particle size distribution, peak viscosity, and final viscosity of the milled product at the initial milling stage. Minimum feed particle size ( ~ 623 μm) has the largest peak viscosity (2, cP 2, cP) after milling 15 min.

احصل على السعرThe results showed that the integrity of the original small spherical structure decreased as the ball milling time increased. Fe 3 O 4 showed excellent microwave absorptions as the milling time reached 2 h, the reflection loss reached the maximum of − dB at GHz as the thickness was mm. View FullText

احصل على السعرThe transformation proceeds in two steps. The first one consists of rapid microstructural rearrangements with continuously increasing αtransformation rate. In the second step (1–2 h from the start), only relatively small changes in morphology are observed with a constant αtransformation rate. The rate is influenced only by the milling intensity.
احصل على السعرThe results showed the structure of composites were highly affected by the increasing amount of nanoSnO 2 particles in reaction medium of hand grinding method than ball milling method. And, the PProDOT/SnO 2 nanocomposites from ball milling method displayed similar absorption spectra, and ball milling method promoted the uniform
