The Dependence of Magnetic and Mechanical Properties on Composition and Processing in Air Fired MnZn Ferrites
The relationship between magnetic and mechanical properties has been studied as a function of composition, atmosphere and temperature for a series of MnZn ferrites. When processed in air, strength and permeability are critically dependent upon the formation of Md+ and ~ e ' + on sintering, and residual stresses introduced via subsequent (re)oxidation upon cooling. In Fe deficient femtes, proper...
متن کاملRelation Between Firing Conditions Grain Boundary Structure and Magnetic Properties in Polycrystalline MnZn-Ferrites
The influence of the firing conditions on the nanoscale structure of the grain boundaries and on the magnetic properties of polycrystalline MnZn-ferrites is investigated, on specimens of nearly identical microstructures. High oxygen partial pressures favor accumulation of impurity ions at the triple points. Under appropriate oxygen pressures homogeneous accumulation of impurities along the grai...

متن کاملThe effect of powder characteristics on pressure sensitivity of powder injection moulding compounds
Pressure effect on the rheological behaviour of powder-polymer compounds intended for powder injection moulding was determined. A single-piston capillary rheometer modified by addition of a second chamber with a restricting needle valve generating backpressure increasing the pressure in the melted material during the flow through the die was employed to determine pressure sensitivity coefficien...
متن کاملMicroporous Titanium through Metal Injection Moulding of Coarse Powder and Surface Modification by Plasma Oxidation
Titanium is one of the most attractive materials for biomedical applications due to having excellent biocompatibility accompanied by good corrosion resistance. One popular processing technique for Ti is Metal Injection Moulding (MIM). However, there are several issues associated with the use of this technique, such as the high cost of the fine powder used, the high level of contamination and co...
