Abstract: Two Fe-Al-Mn alloys with different aluminium and manganese contents were melted in a 90 kW, self-designed, non-consumable plasma torch furnace. Nitrogen was then injected through a bottom porous plug into the molten bath. The solidified ingots were subjected to proper homogenisation and hot forging. It found that the Fe-5Al-11Mn alloy exhibits the highest nitrogen content of 1230 ppm while the elongation as high as 42.2% with level of 804 MPa has been obtained.

Keywords: copper; Fe-Al-Mn-N alloys; low gas contents; new alloys; plasma melting; aluminium; manganese; hot forging; nitrogen; iron.
