Abstract On the basis of our previous investigation, an Fe-Mn-Al steel containing 29.4％Mn, 3.8％ Al, 1.9％ Mo, 0.5％ V, 0.4％ W, 0.015％ B, 0.03％ N and 0.1％ C hasbeen studied systematically. Its workability is similar to that of 1Cr_(18)Ni_9Ti. The stress-rupture properties arecomparable to those of high Cr-Ni austenitic steels, such as ЭИ257Т (14％ Cr, 14％ Ni,2.15％ W, 0.5％ Mo, 0.5％ Ti, 0.1％ C) at 600°and 650℃ for several thousandhours. On ageing at temperatures from 600°to 750℃ for periods up to 9500 hours, ac-companied by changes in hardness, the following phases appeared with increasing ageingtime and temperature: γ V_4C_3, M_6C and AB_2 (Laves phase). The impact value de-creased from about 37 to 10 kg·m/cm~2 after 9500 hours at 650°and 700℃.
