Structural Analysis and Magnetic Properties of FeCo Alloys Obtained by Mechanical Alloying
Journal of Metallurgy, Volume 2016, Issue 1, 2016., 2016 A systematic study on the structural and magnetic properties of Fe100−xCox alloys (10 < x < 90, Δx = 10 in wt. percent) obtained by mechanical alloying is presented. Elemental powders of Fe and Co mixed in an adequate weight ratio were milled at room temperature in a shaker mixer mill using vials and balls of hardened steel as milling media with a ball

Alumina‐Based Ceramics for Armor Application: Mechanical Characterization and Ballistic Testing
Journal of Ceramics, Volume 2014, Issue 1, 2014., 2014 The aim of this work is to present results of mechanical characterization and ballistic test of alumina‐based armor plates. Three compositions (92, 96, and 99 wt% Al2O3) were tested for 10 mm thick plates processed in an industrial plant. Samples were pressed at 110 MPa and sintered at 1600°C for 6 h.

Parameter Optimization in the Synthesis of BZT Ceramics to Achieve Good Dielectric Properties
Journal of Materials, Volume 2013, Issue 1, 2013., 2013 The powder synthesis of barium zirconate titanate (BZT) (BaZrxTi(1 − x)O3) from the mechanochemical activation of BaCO3, ZrO2, and TiO2 was studied. The grinding effect, by using a planetary ball milling, on the crystallization temperature of BZT powders (x = 0.05) was analyzed.

Electrochemical Method for Ag‐PEG Nanoparticles Synthesis
Journal of Nanoparticles, Volume 2013, Issue 1, 2013., 2013 In this work we present an electrochemical method to successfully prepare silver nanoparticles using only polyethylene glycol as stabilizer and without any other reactive. Here we study the use of the polymeric stabilizer to allow the introduction of a potential tool to reinforce the control of the size and shape of the nanoparticles throughout the ...
