Novel nano-composite powders composed of hard-magnetic Mn54Al46 and soft-magnetic α-Fe were prepared by high-energy ball milling. The effect of α-Fe and preparation conditions on the structure and magnetic properties of the composite powders has been investigated. The ε-MnAl transforms to γ-MnAl, τ-MnAl, and β-phase under ball milling and annealing. The saturation magnetization and coercivity of the two-phase samples decrease with increasing temperature for the τ-phase decomposes at elevated temperatures. With increasing iron content, the coercivity decrease first and then increase up to 0.33 T when the Fe content is 10 wt%. Further addition of the magnetically soft iron phase would result in a decrease of the coercivity.

High Nitrogen Stainless Steel

High nitrogen nanostructured Fe-17Cr-11Mn-3Mo stainless steel powders were produced by high energy ball milling under a nitrogen atmosphere. It was found with increasing the milling time, the nitrogen contents of the powder mixtures increase linearly up to 1.98 wt pct after 96h, and a linear regression equation, WN = 0.19357 + 0.01887t , has been further established. In addition, with the increased milling time, the crystallite sizes and particle sizes of the powders decrease continuously, the lattice strains and sphericity of the powders increase gradually. After milling 60h, the high nitrogen nanocrystalline stainless steel powders with a fine particle size range of 5~10μm, excellent sphericity and uniform components can be obtained, whose crystallite size is about 5.0nm and lattice strain is about 1.0%. The powders milled for 60h was compacted using spark plasma sintering process at different temperatures. It is found that a fully austenitic high nitrogen stainless steel with almost full densification can be obtained by SPS at 1000°C, whose nitrogen content is 0.82 wt pct.

The effects of milling speed and calcinations temperature towards La0.6Sr0.4CO0.2Fe0.8O3-δ-SDC carbonate (LSCF-SDC carbonate) composite cathodes were investigated. The preparation of samarium-doped ceria (SDC) carbonate was firstly done by milling the SDC nanopowder with carbonate using the high-energy ball milling (HEBM) in air at room temperature. The obtained SDC carbonate was then used to mill with composite powder of lanthanum strontium cobalt ferrite (LSCF) which is one of the promising materials for the cathode of solid oxide fuel cells (SOFC). The purpose of milling LSCF composite powder with SDC carbonate was to get new composite cathode for intermediate-to low-temperature solid oxide fuel cells (IT-TLSOFC). LSCF composite powder with SDC carbonate was milled using high-energy ball milling with milling speed of 150 rpm and 550 rpm and calcinations temperatures of 750°C, 800°C, 850°C and 900°C. Field emission scanning electron microscopy (FESEM) analysis revealed the presence of large particle resulting from the increasing of calcinations temperature. FESEM also shows the particle size decrease in size with the increasing of milling speed. Therefore, the speed of 550 rpm and temperature of 900°C were found to be the best milling speed and calcinations temperature in producing the composite cathode of LSCF-SDC carbonate.
