Impact Energy of Functionally Graded Steels in Crack Arrester Configuration
Journal of Materials Engineering and Performance - Tập 19 - Trang 1058-1064 - 2009
A. Nazari, J. Aghazadeh Mohandesi
Charpy impact energy of functionally graded steels produced by electroslag remelting composed of graded ferrite and austenite layers together with bainite or martensite intermediate layer in the form of crack arrester configuration has been investigated. The results obtained in the present study indicate that the notch tip position with respect to bainite or martensite layer significantly affects ...... hiện toàn bộ
Effect of Ho Content and Heat Treatment on the Corrosion Resistance of Mg-xHo-3Sm-0.5Zr Alloy
Journal of Materials Engineering and Performance - Tập 32 - Trang 7785-7795 - 2022
Hang Leng, Quanan Li, Xiaoya Chen, Hongxi Zhu, Jun Chen, Peijun Chen, Jinfeng Tan, Xiangyu Li
The corrosion resistance of as-cast Mg-xHo-3Sm-0.5Zr, solid solution and aged Mg-8Ho-3Sm-0.5Zr alloys was studied by electrochemical experiments, weight loss tests and microstructure analysis. The results showed that adding a proper amount of Ho to the as-cast alloy can refine the grain size. Furthermore, Ho can promote the precipitation of the Mg41Sm5 phase and form a new Mg24Ho5 phase. The Mg-8H...... hiện toàn bộ
Effect of Retrogression and Re-aging Treatment on Properties and Microstructure of a New Type of Al–Zn–Mg–Er–Zr Alloy
Journal of Materials Engineering and Performance - Tập 31 - Trang 4282-4293 - 2022
H. Wu, Z. K. Zheng, W. C. Li, J. T. Lu, S. P. Wen, H. Huang, Z. R. Nie
The effect of retrogression and re-aging treatment (RRA) on properties and microstructure of a new type of Al–Zn–Mg–Er–Zr alloy are investigated. The results show that extending retrogression time is beneficial to improve intergranular corrosion (IGC) and exfoliation corrosion (EXCO) resistance but decreases the strength. The mechanical properties and corrosion resistance of the studied alloy are ...... hiện toàn bộ

Disk Laser Weld Brazing of AW5083 Aluminum Alloy with Titanium Grade 2
Journal of Materials Engineering and Performance - Tập 26 - Trang 1346-1357 - 2017
Miroslav Sahul, Martin Sahul, Maroš Vyskoč, Ľubomír Čaplovič, Matej Pašák
Disk laser weld brazing of dissimilar metals was carried out. Aluminum alloy 5083 and commercially pure titanium Grade 2 with the thickness of 2.0 mm were used as experimental materials. Butt weld brazed joints were produced under different welding parameters. The 5087 aluminum alloy filler wire with a diameter of 1.2 mm was used for joining dissimilar metals. The elimination of weld metal crackin...... hiện toàn bộ
Microstructure and Mechanical Properties of the Extruded Al-Cu-Mn-Sc-Zr Alloy during Single-Stage and Two-Stage Aging
Journal of Materials Engineering and Performance - Tập 32 - Trang 185-198 - 2022
Zhiyong Cai, Haijiang Liu, Richu Wang, Chaoqun Peng, Yan Feng, Xiaofeng Wang
The evolution of microstructure and mechanical properties of hot extruded Al-5.5Cu-Mn-Sc-Zr and Al-6.5Cu-Mn-Sc-Zr alloys during solution and different aging treatments was investigated. The typical fibrous structure and elongated grains along the extrusion direction were observed in the two alloys. After solution and aging treatments, the proportion of large-size grains in the alloys increases sli...... hiện toàn bộ

SECM Study of Effect of Chromium Content on the Localized Corrosion Behavior of Low-Alloy Steels in Chloride Environment
Journal of Materials Engineering and Performance - Tập 25 - Trang 4157-4170 - 2016
K. Indira, T. Nishimura
This paper investigates the effect of chromium (Cr) content (0, 1, 3 and 5% Cr) in epoxy-coated alloy steel against corrosion using in situ electrochemical techniques such as EIS and SECM in a 3% NaCl solution. The EIS results revealed that the epoxy-coated Cr steel exhibited higher impedance values than carbon steel, which is attributed to the greater resistance of Cr steel toward corrosion.

Effect of Nd on the Microstructure and Mechanical Properties of Hot Extruded Mg-2.0Sm-0.4Zn-0.4Zr Alloy
Journal of Materials Engineering and Performance - - 2022
Kun Liu, Sicong Zhao, Zhiwei Wang, Yicheng Feng, Changliang Wang, Lei Wang, Dongrong Liu, Jingfang Li
The development of magnesium alloys with superior plasticity and favorable strength is still challenging in aerospace industry. Herein, hot extruded Mg-xNd-2.0Sm-0.4Zn-0.4Zr alloys (x = 0, 0.5, 1.0, 1.5, 2.0 and 2.5 wt.%) were rationally designed and easily prepared in order to implement the favorable combination of strength and plasticity. The effects of Nd element addition on the microstructure ...... hiện toàn bộ
