Abstract
This paper describes the effect of the sintering parameters, e.g. temperature and atmosphere, on the microstructure and phase composition of the cobalt-iron materials. Investigations were carried out on the specimens made of the mixtures of elemental cobalt and iron powders, containing 3, 6, 10, 15 and 25 wt.% iron addition. Samples were obtained by cold pressing under 400 MPa then sintered at 900 and 1150 °C for an hour. As a sintering atmospheres both flowing, purified hydrogen and nitrogen was used. The obtained results have shown that density of Co-Fe materials strongly depends on iron content, whereas sintering atmosphere has a minor effect on their hardness. Microstructural investigations have shown that applied sintering atmosphere plays a significant role if grain size and cobalt's phase composition are taken under consideration.
