 · Nanoparticles of Fe and NdFeB alloy with sizes less than 20 nm were fabried by H. G. Cha et al[118] by a highenergy ball milling process in the presence of surfactant and organic carrier liquid. It was also observed that the Fe and NdFeB alloy nanoparticles were phasetransformed from an amorphous to crystalline state by a heat treatment. This phase .

no reaction during milling (up to 80 h) with ZrO2 cup and balls. Fe and ZrO2 were the major impurities introduced during milling with stainless steel and ZrO2 cups, respectively. The Fe impurity was removed by leaching in 3HCl·HNO3 solution for 4 days. Mean grain size less than 7 nm was achieved at the end of milling. In spite of grain growth, this composite maintained its .

High energy ball milling has been shown to be a promising method for largescale fabriion of rare earthtransition metal nanoparticles. In this work, magnetically hard NdFeB nanopowders with a coercivity in the range of kOe have been produced by surfactantassisted ball milling of nanocrystalline precursor alloys. The nanopowders consisted of .

ball milling (HEBM) from SmCo5 and 5%wt. of Fe powders. The Xray diffraction analysis reveals the hexagonal 1:5 phase as the main one accompanied by the cubic Fe phase and 2:17 rhombohedral as the secondary phase. The content of each detected phase is modified throughout the synthesis duration. A significant decrease in crystallite size with a .

In particular, mechanical attributed contamination by the milling tools (Fe or WC) as well as ambient gas (trace impurities such as O 2, N 2 in rare gases) can be problems for highenergy ball milling. However, using optimized milling speed and milling time may effectively reduce the contamination. Moreover, ductile materials can form a thin coating layer on the milling tools .

Abstract A series of SrTi1−xFexO3−δ (STO or STFO) powders, with x ranging from 0 to, were prepared by selfpropagating hightemperature synthesis (SHS) starting from SrO2, Ti, TiO2 and Fe. A ballmilling (BM) treatment was subsequently carried out for further structure refinement and size reduction. Morphological and microstructural characteristics of both untreated and .
