Abstract

The manufacturing of electrical converter using powder-metallurgy can be
considered as acomplex-subject due to the several variables which include
for examples, selection of raw materials, purity, and grain size. There are
many researches that have been used to study iron-nickel, iron-silicon, and
so on, but the research on iron-cobalt in our country is limited and due to
the significance of core-industrial in electrical converters, barometer and
computer devices…….etc, this work has included:
1. Preparing compacted-materials of (Fe1-xCox) by using powdermetallurgy
at different weight ratios (x=15, 25, 35, 50).
2. studying the effect of time and temperature of sintering on magnetic
properties ( permeability, coercivity force, and hystersis loop) for
materials prepared by using powder-metallurgy.
3. studying the effect of different ratios of pure cobalt-powder added on
magnetic properties and microstructure of prepared materials.
4. produceing different shapes and sizes of electrical-core
