Research Progress and Prospect of High-Entropy Alloy Materials

Li Tianxin, Wang Shudao, Lu Yiping, Cao Zhiqiang, Wang Tongmin, Li Tingju

Strategic Study of CAE 2023, Volume 25, Issue 3,   Pages 170-181 doi: 10.15302/J-SSCAE-2023.03.016

Abstract:

With the rapid development of world’s technological level and the urgent demand of national economic construction for high-performance alloy materials, traditional single-component alloys gradually fail to satisfy the increasing service requirements. Owing to their unique physical, chemical, and mechanical properties, high-entropy alloys are expected to play an important role in major engineering fields such as national defense, aviation, aerospace, marine, nuclear energy, medical care, and new energy, greatly expanding the design range of metal material compositions. In this paper, based on the specific demands of advanced high-entropy alloy materials in various fields, the characteristics and connotations of high-entropy alloy materials are summarized, and the overall situation and prospects of high-entropy alloy material development are analyzed, as well as the current status of high-entropy alloy development in China and abroad. On this basis, the gaps and deficiencies in the field of high-entropy alloys in China are pointed out. First, some basic raw materials of the high-entropy alloys still rely on imports, which severely threatens the security of the industrial chain. Second, the research and development investment in industrial application of high-entropy alloys needs to be increased, and the industrial–academia–research–application system of high-entropy alloys is not yet sound. Regarding the above-mentioned issues, this study proposes the following policies and measures: strengthening the top-level design of high-entropy alloy material research and development while improving industrial policies; strengthening the connection and communication between enterprises and research institutes; improving the standardization, testing, characterization, and evaluation systems of high-entropy alloy materials; advancing the construction of talent teams; and reducing material costs and creating high value-added products, to promote the systematic, green, high-end, and intelligent development of China’s advanced high-entropy alloy material industry.

Enhanced carbon tetrachloride degradation by hydroxylamine in ferrous ion activated calcium peroxide

Wenchao Jiang, Ping Tang, Zhen Liu, Huan He, Qian Sui, Shuguang Lyu

Frontiers of Environmental Science & Engineering 2020, Volume 14, Issue 2, doi: 10.1007/s11783-019-1197-1

Abstract: Complete CT degradation was achieved by employing HA to CP/Fe(II)/FA process. Quantitative detection of Fe(II) regeneration and HO• production was investigated. Benzoic acid outcompeted FA for the reaction with HO•. CO2•− was the dominant reductive radical for CT removal. Effects of solution matrix on CT removal were conducted. Hydroxyl radicals (HO•) show low reactivity with perchlorinated hydrocarbons, such as carbon tetrachloride (CT), in conventional Fenton reactions, therefore, the generation of reductive radicals has attracted increasing attention. This study investigated the enhancement of CT degradation by the synergistic effects of hydroxylamine (HA) and formic acid (FA) (initial [CT] = 0.13 mmol/L) in a Fe(II) activated calcium peroxide (CP) Fenton process. CT degradation increased from 56.6% to 99.9% with the addition of 0.78 mmol/L HA to the CP/Fe(II)/FA/CT process in a molar ratio of 12/6/12/1. The results also showed that the presence of HA enhanced the regeneration of Fe(II) from Fe(III), and the production of HO• increased one-fold when employing benzoic acid as the HO• probe. Additionally, FA slightly improves the production of HO•. A study of the mechanism confirmed that the carbon dioxide radical (CO2•−), a strong reductant generated by the reaction between FA and HO•, was the dominant radical responsible for CT degradation. Almost complete CT dechlorination was achieved in the process. The presence of humic acid and chloride ion slightly decreased CT removal, while high doses of bicarbonate and high pH inhibited CT degradation. This study helps us to better understand the synergistic roles of FA and HA for HO• and CO2•− generation and the removal of perchlorinated hydrocarbons in modified Fenton systems.

Research on Development Situation of Ferrous Metal Resources in China

Task Group for the Strategic Research on Great Power of Ferrous Metal Mineral Resources

Strategic Study of CAE 2019, Volume 21, Issue 1,   Pages 97-103 doi: 10.15302/J-SSCAE-2019.01.014

Abstract:

 As a forerunner of the supply-side structure reform, China’s iron and steel industry actively resolves its overcapacity. More than 1.2×108 t of excessive steel production capacity has been resolved between 2016 and 2017, and 1.4×108 t of illegal production capacity, such as “substandard steel” has been eliminated. As the global iron and steel industry is currently in the excess production capacity cycle, China's steel consumption has developed from a sustained growth phase to a peak value platform area. Meanwhile, both the crude steel consumption intensity per unit GDP and that per unit investment has decreased. It is expected that the consumption demand and output of crude steel in China will reach 6×108-6.5×108 t and 6.5×108-7.0×108 t by 2025, respectively; and these same items will reach 5.3×108-6.0×108 t and 5.9×108-6.5×108 t by 2030, respectively. Meanwhile, the supply of steel scrap resources in China will increase rapidly, and the sufficient steel scrap resources will become a strong support for China’s iron and steel industry. The structure of iron resources will also be greatly changed, and the demand for international iron ore resources will decrease gradually. All the changes are important in promoting ecological civilization construction and green development.

network model on tensile behavior of hybrid steel-PVA fiber reinforced concrete containing fly ash and slag

Fangyu LIU, Wenqi DING, Yafei QIAO, Linbing WANG

Frontiers of Structural and Civil Engineering 2020, Volume 14, Issue 6,   Pages 1299-1315 doi: 10.1007/s11709-020-0712-6

Abstract: The tensile behavior of hybrid fiber reinforced concrete (HFRC) is important to the design of HFRC and HFRC structure. This study used an artificial neural network (ANN) model to describe the tensile behavior of HFRC. This ANN model can describe well the tensile stress-strain curve of HFRC with the consideration of 23 features of HFRC. In the model, three methods to process output features (no-processed, mid-processed, and processed) are discussed and the mid-processed method is recommended to achieve a better reproduction of the experimental data. This means the strain should be normalized while the stress doesn’t need normalization. To prepare the database of the model, both many direct tensile test results and the relevant literature data are collected. Moreover, a traditional equation-based model is also established and compared with the ANN model. The results show that the ANN model has a better prediction than the equation-based model in terms of the tensile stress-strain curve, tensile strength, and strain corresponding to tensile strength of HFRC. Finally, the sensitivity analysis of the ANN model is also performed to analyze the contribution of each input feature to the tensile strength and strain corresponding to tensile strength. The mechanical properties of plain concrete make the main contribution to the tensile strength and strain corresponding to tensile strength, while steel fibers tend to make more contributions to these two items than PVA fibers.
