“…S. Sun et al [ 31 ] studied the AFA steel, Fe-16Cr-3Al-2W-0.3Si-0.4Nb-0.04Y, and found that at a strain of 0.1, the optimal hot working condition occurred in the temperatures range of 1050–1075 °C and strain rates range of 0.03 s −1 -0.3 s −1 . Rui Luo et al [ 106 ], Min-Ho Jang et al [ 53 ], and Qiuzhi Gao et al [ 113 ] carried out thermal simulation tests on the hot workability of the studied AFA steel and obtained the suitable temperatures and strain rate for hot working.…”

The development of Alumina-Forming Austenitic (AFA) stainless steel is reviewed in this paper. As a new type of heat-resistant steel, AFA steel forms an alumina protective scale instead of chromia in a corrosive environment. This work summarizes the types of developed AFA steels and introduces the methods of composition design. Various precipitates appear in the microstructure that directly determine the performance at high temperatures. It was found that alloy elements and the heat treatment process have an important influence on precipitates. In addition, the corrosion resistance of AFA steel in different corrosive environments is systematically analyzed, and the beneficial or harmful effects of different elements on the formation of alumina protective scale are discussed. In this paper, the short-term mechanical properties, creep properties and influencing factors of AFA steel are also analyzed. This work aims to summarize the research status on this subject, analyze the current research results, and explore future research directions.

Niobium bearing ultralow carbon micro alloyed dual phase steel grade steel with chemical composition of 0.045 wt.% carbon, 0.04 wt.% niobium, 0.59 wt.% chromium, 0.9 wt.% manganese, 0.28 wt.% silicon is investigated. The design of thermomechanical treatment needs knowledge about the flow behaviour at high deformation temperatures, to be used for this steel in industrial plants. Therefore, this work aims to predict, for the investigated steel, the flow behaviour and mean flow stress. A phenomenological constitutive model is established to derive the flow stress using the hyperbolic sinusoidal Arrhenius mathematical model. The relation between stress and strain with Zener‐Hollomon parameter is studied. Mean flow stress has been figured out by measurements taken from compact slab production plant log data using a constitutive model. The constitutive model is further verified by multiple hits of flat compression setup mode at BährTTS820 physical simulator. The tests were performed under specific thermochemical schedule simulating compact slab production plant. The results show good agreement between the calculated flow stress, Non‐recrystallization temperature and experimentally measured values obtained from the physical simulation. Ferrite grain size is modelled and predicted then validated by experimental rolled specimens in a practical hot strip mill.

“…Hot workability is defined as the simplicity with which the metals and alloys deform plastically at high temperatures without the risk of fracture or other damage mechanisms. In different materials, enhancement of hot workability can be obtained by an appropriate combination of hot deformation parameters such as strain, strain rate and temperature [9][10][11]. The correct selection of hot working parameters will lead to restoration phenomena such as dynamic recrystallization and dynamic recovery, which in turn will improve the workability, microstructural and mechanical properties of the hot deformed alloy [12][13][14].…”

“…Processing maps define the efficiency of hot working procedures as well as the flow instability of materials. At present, many researchers have used the processing maps to investigate the hot workability of various materials [10][11][12][13][14][17][18][19][20]. Investigation of the hot deformation behavior of N-155 alloy to clarify the hot working characteristics and microstructural features can be valuable to optimize the product manufacturing and its properties.…”

Hot deformation behavior of iron-nickel based superalloy (multimet N-155) was investigated by hot compression tests, carried out in the deformation temperature of 850°C-1150°C with strain rates of 0.001-0.1 s À 1 . The results showed that during the hot deformation of the alloy, under the same temperature, the flow stress rises with the increase of strain rate. At the same strain rate, the flow stress decreases with the increase of the temperature. The constitutive equations of the alloy that describe the flow stress as a function of strain rate and deformation temperature were established and the calculated apparent activation energy was 584.996 Kj/ mol. The results of metallographic analysis showed that the amount of dynamic recrystallization in the peak efficiency domain is higher than the other domains.The results also showed that by increase of deformation temperature and/or decrease of strain rate, the volume fraction of dynamic recrystallization increases. Processing maps under different strains were constructed for evaluation of flow instability regime and optimization of processing parameters. The optimum hot working window for alloy was obtained at the temperature range of 925°C-1050°C and strain rate of 0.001-0.003 s À 1 , with peak efficiency of 28 %.
