摘要: 配制了30个不同成分的鋼种,对Fe-Mn-Al系奥氏体鋼,进行了成分、組織結构、性能方面的研究。在研究的成分范围內,找出了奥氏体区与成分的經驗关系;观察了成分及組織結构对高低溫瞬时力学性能、持久强度、时效性能、抗氧化性能等的影响;得到了在650℃持久强度相当于257T的实驗鋼种,并初步确定了在Fe-Mn-Al系中发展出耐热鋼种的最可能成分范围。指出了在实驗鋼种A2的基础上,发展出无磁钢及低溫鋼的可能性。
Abstract:The possibility of the development of Fe-Mn-Al austenitic steels has been investigated with special attention paid to the effect of Mo, W, Ti, V, Cr or Si on the stability of austenite, their high-temperature strength and tonghness, as well as their resistance to oxidation and corrosion.It was found that two alloys have good tensile and stress-rupture properties comparable to those of high Cr-Ni bearing steels such as 257 Ti and one alloy has oxidation resisting property similar to that of 13% Cr steel. However, their corrosion resistance is rather poor and this seems to be the main objection for them to be used as high-temperature steels. Cladding and surface coating are suggested as possible remedies.Some of the alloys have low magnetic permeability and high impact values at-178℃, thus enabling them to be considered as potential non-magnetic and low-temperature steels.
