We have observed from X-ray diffraction that a nonequilibrium solid solution could be obtained up to 35 at.% Si within 100 h of milling. Although these powders have fine crystallites with size ranging around 9 nm, their coercivity is rather high, which depends strongly both on milling condition and composition. While saturation magnetization ( MS) decreases continuously, coercivity shows a nonlinear variation with Si substitution. The variations of MS and lattice constant with Si substitution show a good correlation between the structural and magnetic properties. Curie temperature of Fe-Si solid solution decreases gradually at a rate of 1.45 K/at.% Si with increasing Si content. The observed results are discussed based on fine crystallite size, development of internal strain and grain boundaries, and variations in effective magnetic anisotropy in the mechanically alloyed nanocrystalline Fe-Si powder.</div> </div> <div class='row'> <div class='leftDiv labelDiv col-xs-4 col-sm-2 fullRecLabelEnglish'>Keywords : </div><div class='valueDiv leftDirection leftAlign col-xs-8 col-sm-10 fullRecValueEnglish'>Curie temperature; X-ray diffraction; ball milling; coercive force; crystal microstructure; crystallites; grain boundaries; iron alloys; lattice constants; magnetic anisotropy; nanofabrication; nanomagnetics; nanoparticles; silicon alloys; solid solutions; Curie temperature; Fe<sub>100-x</sub>Si<sub>x</sub>; X-ray diffraction; coercivity; crystallites; grain boundaries; high energy ball milling; lattice constant; magnetic anisotropy; magnetic properties; milling; nanocrystalline alloy powders; nanocrystalline microstructure; nonequilibrium solid solution; saturation magnetization; structural properties; Iron; Magnetic properties; Milling; Powders; Silicon; Solids; Curie temperature; dislocation density; magnetic properties; mechanical alloying (MA); nanocrystalline (NC) materials;</div> </div> <div class='row'> <div class='leftDiv labelDiv col-xs-4 col-sm-2 fullRecLabelEnglish'>fLanguage : </div><div class='valueDiv leftDirection leftAlign col-xs-8 col-sm-10 fullRecValueEnglish'>English</div> </div> <div class='row'> <div class='leftDiv labelDiv col-xs-4 col-sm-2 fullRecLabelEnglish'>Journal_Title : </div><div class='valueDiv leftDirection leftAlign col-xs-8 col-sm-10 fullRecValueEnglish'>Magnetics, IEEE Transactions on</div> </div> <div class='row'> <div class='leftDiv labelDiv col-xs-4 col-sm-2 fullRecLabelEnglish'>Publisher : </div><div class='valueDiv leftDirection leftAlign col-xs-8 col-sm-10 fullRecValueEnglish'>ieee</div> </div> <div class='row'> <div class='leftDiv labelDiv col-xs-4 col-sm-2 fullRecLabelEnglish'>ISSN : </div><div class='valueDiv leftDirection leftAlign col-xs-8 col-sm-10 fullRecValueEnglish'>0018-9464</div> </div> <div class='row'> <div class='leftDiv labelDiv col-xs-4 col-sm-2 fullRecLabelEnglish'>Type : </div><div class='valueDiv leftDirection leftAlign col-xs-8 col-sm-10 fullRecValueEnglish'>jour</div> </div> <div class='row'> <div class='leftDiv labelDiv col-xs-4 col-sm-2 fullRecLabelEnglish'>DOI : </div><div class='valueDiv leftDirection leftAlign col-xs-8 col-sm-10 fullRecValueEnglish'>10.1109/TMAG.2013.2278555</div> </div> <div class='row'> <div class='leftDiv labelDiv col-xs-4 col-sm-2 fullRecLabelEnglish'>Filename : </div><div class='valueDiv leftDirection leftAlign col-xs-8 col-sm-10 fullRecValueEnglish'>6692970</div> </div> <div class='row'> <div class='leftDiv labelDiv col-xs-4 col-sm-2 fullRecLabelEnglish'>Link To Document : </div><div class='valueDiv leftDirection leftAlign fullRecValueEnglish col-xs-8 col-sm-10'><a href='https://search.ricest.ac.ir/dl/search/defaultta.aspx?DTC=49&DC=38659' target='_blank'>https://search.ricest.ac.ir/dl/search/defaultta.aspx?DTC=49&DC=38659</a></div> </div> </div> <div class='leftDiv labelDiv leftAlign backLinkEnglish'><a href='javascript:history.back()'><img src='../CSS/Back.png' class='backImage' alt=
