Abstract

The use of traditional materials leads to failures and breakdowns of expensive equipment, so advanced materials are needed that can provide reliable and durable solutions. The ability to control the quality of duplex stainless steels (DSSs) can greatly help with the development of new compositions or choosing existing DSSs. In this case, it is necessary to consider the final consumer properties-corrosion resistance and mechanical properties, which depend on the phase composition, contamination with non-metallic inclusions (NMIs), and the presence of undesirable secondary phases. In this research, specimens of cast DSSs of different grades, produced at laboratory and industrial scales, were studied. A technique for quantifying the microstructure of DSSs was developed. A thermodynamic database was chosen that adequately describes the processes of phase formation in DSSs. The effects of heat treatment on the microstructure and corrosion properties of cast DSSs were studied. The effects of the structural state on the changes in consumer properties of the final product are shown. It is shown that using various deoxidation technologies, it is possible to obtain both NMIs that are dangerous in terms of corrosive activity and ones that are relatively safe.

摘要

使用传统材料会导致昂贵设备出现故障和损坏，因此需要先进材料来提供可靠且耐用的解决方案。控制双相不锈钢（DSS）质量的能力对新成分的开发或现有DSS的选择有很大帮助。在这种情况下，有必要考虑最终的使用性能——耐腐蚀性和机械性能，这取决于相组成、非金属夹杂物（NMI）的污染以及不良次生相的存在。在本研究中，对实验室和工业规模生产的不同等级铸造DSS试样进行了研究。开发了一种量化DSS微观结构的技术。选择了一个能充分描述DSS中相形成过程的热力学数据库。研究了热处理对铸造DSS微观结构和腐蚀性能的影响。展示了结构状态对最终使用性能变化的影响。结果表明，使用各种脱氧技术，既可能获得在腐蚀活性方面危险的NMI，也可能获得相对安全的NMI。
