Abstract: Methods for the production of magnetic powders, compacted magnetic bodies and sintered magnetic bodies. The methods include the use of metal carboxylate precursor compounds such as metal oxalates. The precursor compounds are heated under pressure to form metal alloy particles which can be directly formed into compacted magnetic bodies or can be further refined by using a reductant at elevated temperatures and pressures. The sintered magnetic bodies may have strong magnetic properties even if produced in the absence of a strong magnetic field.

Abstract: A method to achieve full densification and grain size control for sintering metal materials, wherein raw material powder is deagglomerated to obtain deagglomerated powder with dispersion. The deagglomerated powder is granulated by spray granulation. The granulated particles are processed by high-pressure die pressing and cold isostatic pressing. The powder compact is sintered by two-step pressureless sintering. The first step is to heat up the powder compact to a higher temperature and hold for a short time to obtain 75-85% theoretical density; the second step is to cool down powder compact to a lower temperature and hold for a long time. The two-step sintering can decrease the sintering temperature, so that the powder compact can be densified at a lower temperature. Thus, the obtained refractory metal product is densified, with ultrafine grains, uniform grain size distribution, and outstanding mechanical properties.
