Evolution of the Corrosion Product Film and Its Effect on the Erosion–Corrosion Behavior of Two Commercial 90Cu–10Ni Tubes in Seawater
Acta Metallurgica Sinica (English Letters) - Tập 31 - Trang 1148-1170 - 2018
Okpo O. Ekerenam, Ai-Li Ma, Yu-Gui Zheng, Si-Yu He, Peter C. Okafor
The composition and structural evolution of the corrosion product film of two commercial 90Cu–10Ni tubes, namely Tube A and Tube B, after being immersed in natural seawater for 1, 3, and 6 months were characterized by scanning electron microscopy, energy-dispersive X-ray spectroscopy, X-ray diffraction, and X-ray photoelectron spectroscopy, and its effect on the erosion–corrosion behavior of the t...... hiện toàn bộ
Superb Strengthening Effect of Net-Like Distributed Amorphous Al2O3 on Creep Resistance of (B4C + Al2O3)/Al Neutron-Absorbing Materials
Acta Metallurgica Sinica (English Letters) - Tập 35 - Trang 2007-2013 - 2022
Y. N. Zan, X. Lei, J. F. Zhang, D. Wang, Q. Z. Wang, B. L. Xiao, Z. Y. Ma
B4C reinforced Al composites are widely used as neutron absorbing materials (NAMs) due to excellent neutron absorbing efficiency, however, such NAMs exhibit poor high-temperature properties. To meet the requirement for structure–function integration, NAMs with enhanced high-temperature mechanical properties are desired. In this work, a novel (B4C + Al2O3)/Al NAM with netlike distribution of Al2O3 ...... hiện toàn bộ

Effect of Axial Magnetic Field on the Microstructure and Mechanical Properties of CrN Films Deposited by Arc Ion Plating
Acta Metallurgica Sinica (English Letters) - Tập 29 - Trang 546-553 - 2016
Yan-Hui Zhao, Li Xu, Chao-Qian Guo, Wen-Jin Yang, Guo-Qiang Lin, Bao-Hai Yu
CrN films were deposited on the high-speed-steel substrates by arc ion plating. The effect of an axial magnetic field on the microstructure and mechanical properties was investigated. The chemical composition, microstructure, surface morphology, surface roughness, hardness and film/substrate adhesion of the film were characterized by X-ray photoelectron spectroscopy, X-ray diffraction, scanning el...... hiện toàn bộ
Effect of Prior Cold Deformation on the Stability of Retained Austenite in GCr15 Bearing Steel
Acta Metallurgica Sinica (English Letters) - Tập 32 Số 1 - Trang 107-115 - 2019
Wang, Feng, Qian, Dong-Sheng, Lu, Xiao-Hui
In this work, the effect of prior cold deformation on the stability of retained austenite in GCr15 bearing steel was investigated after quenching and tempering treatment. The thermal stability was evaluated by calculating thermal activation energy for decomposition of retained austenite using differential scanning calorimeter. The mechanical stability was investigated according to the strain-induc...... hiện toàn bộ
Influence of Vanadium Content on Hot Deformation Behavior of Low-Carbon Boron Microalloyed Steel
Acta Metallurgica Sinica (English Letters) - Tập 33 - Trang 705-715 - 2020
Kwang-Su Kim, Lin-Xiu Du, Hyo-sung Choe, Tae-Hyong Lee, Gyong-Chol Lee
Single-pass compression tests were performed to investigate the hot deformation behavior of low-carbon boron microalloyed steel containing three various vanadium contents at 900–1100 °C and strain rate of 0.01–10 s−1 using the MMS-300 thermal mechanical simulator. The flow stress curves of investigated steels were obtained under the different deformation conditions, and the effects of the deformat...... hiện toàn bộ

Effect of Isothermal Temperature on Microstructure and Mechanical Properties of High Al–Low Si TRIP Steel
Acta Metallurgica Sinica (English Letters) - Tập 27 - Trang 389-394 - 2014
Yang Zhao, Qiangjun Yan, Liqing Chen, Xiaoyun Yuan
In this study, the effect of isothermal temperature on microstructure and mechanical properties of a high Al–low Si TRIP steel was investigated using scanning electron microscopy, transmission electron microscopy, X-ray diffraction, electron back scattered diffraction, and tensile test. The results show that typical microstructure containing ferrite, bainite, and retained austenite can be obtained...... hiện toàn bộ
