Abstract


An experimental study on green density of iron and ferromanganese mixed powders was done. The influence of added Mn up to 15 wt. %  to Fe powder on the compressibility has been investigated. Cylindrical specimens of mixed iron powder (DWP400) and ferromanganese powder (FeMn80C20) were made. The samples were bilaterally pressed at 100 to 600 MPa. Pressed samples were analyzed by density measurements and also by numerical method. The density of mixed powders decreases as the manganese content increases, and have the maximum value for a content of 5 wt. % Mn.

Key words: density, manganese, iron, simulation
