Structure and properties of Fe-6.67% C alloy obtained by mechanical alloying

The test material was the mixture of Fe and C powders obtained by the mixing of the graphite powder with the iron powder in the proportion of 6.67% C:93.33% Fe (mass%). The powders were ground for the following time intervals: 10, 25, 50, 75 and 100 h. The microscopic observation of the shape and size of the powdered material grains was carried out by the scanning electron microscope provided within the magnification of 100-2000 times. The changes of the powder structure were tested by means of the X-ray diffractometer.
