摘要：
We observed direct evidence that 18R martensite is induced by carbon atoms in the BCC grains of an Fe-27.0wt.%Mn-5.3wt.%Al-0.1wt.%C alloy via high-temperature quenching. A single BCC phase structure formed 18R martensite in the present study. The lowest carbon content found for the formation of 18R martensite is 0.035 wt.% in Fe-Mn-Al alloys.
