《Relationship between the microstructure and properties of thermomechanically processed Fe-17Mn and Fe-17Mn-3Al steels》
Both the Fe-17Mn and Fe-17Mn-3Al（wt%，so as the follows）steels were prepared in a high-frequency air induction furnace.According to the stoichiometric calculations，initially required amounts of mild steel and cast iron were heated to 1580°C for 15 min，and then high-purity Mn and Al were added.In the air induction furnace，to minimize the oxidation of the melt，the furnace top was covered with a ceramic block with a hole through its center，through which a stirrer was inserted into the melt.The melt was continuously stirred for 10 min to avoid the segregation of Al.The molten material was then poured into a preheated metallic mold（200°C）；the pouring temperature was 1580°C.Table 1 shows the compositions of the Fe-17Mn and Fe-17Mn-3Al steels.The weight of the as-cast（AC）ingot was 25 kg，and its dimensions were 457.2 mm×152.4 mm×101.6 mm.
