Effect of cold rolling reduction on the precipitation behavior of σ phase in 2906 duplex stainless steel

Journal of Materials Research and Technology (2023)

Jingkun Li Bin-guo Fu Tian-shun Dong Guolu Li Wenqing Sheng

The effect of cold rolling reduction on the precipitation of σ phase at 800 °C in the 2906 DSS was investigated. The results show that the precipitation rate of the σ phase is improved with the increase of rolling reduction, and the maximum volume fraction is limited to 15%–20% due to the exhaust of ferrite. Improving the rolling reduction could promote the diffusion of Cr, Ni, Mo departing from ferrite and Ni, Mo departing from austenite during the following aging process. The contents of Cr, Ni and Mo increased suddenly and then keep stable in the σ phase, which preferentially nucleated around the narrow ferrite regions. The increase of cold rolling reduction is favorable for σ phase precipitation due to the promoted diffusion of Cr, Ni and Mo elements, as well as the decrease in thickness of ferrite/austenite lamellar interface. The σ phase/austenite interface is incoherent without orientation relationship between the σ phase and austenite, the orientation relationship between ferrite and austenite illustrates (02-2)γ//(-13-2)α and (33-1)γ//(-33-2)α, and the σ phase becomes coarsen and continuous along the ferrite/austenite interface.

Microstructure and Properties of Cold Sprayed NiCrAl Coating on AZ91D Magnesium Alloy

Coatings (2021)

Xuechuang Zhao Tian-shun Dong Bin-guo Fu Guolu Li Qi Liu

Herein, a NiCrAl coating was prepared on the AZ91D magnesium alloy by cold spraying technology. The microstructure, wear resistance, and corrosion resistance of the cold sprayed NiCrAl coating were studied and compared with two NiCrAl coatings prepared by plasma spraying. The results showed that the porosity of the two-plasma sprayed NiCrAl coatings was 3.21% and 2.66%, respectively, while that of the cold sprayed NiCrAl coating was only 0.68%. The hardness of the cold sprayed NiCrAl coating (650 HV0.1) was higher than those of the two-plasma sprayed NiCrAl coatings (300 HV0.1, 400 HV0.1). In the abrasion resistance test, the cold sprayed NiCrAl coating showed a lower friction coefficient (0.346), less wear volume (3.026 mm3), and superior wear resistance accordingly compared with the two-plasma sprayed NiCrAl coatings. Moreover, the scanning electron microscopy (SEM) morphology at the bottom of the wear trace of the cold sprayed NiCrAl coating showed a compact mechanically mixed layers (MML) structure, and its wear mechanism was mainly abrasive wear, with some fatigue wear. In the electrochemical test, the corrosion current density of the cold sprayed NiCrAl coating (4.404 × 10−2 A·cm−2) was much lower than those of two plasma sprayed coatings (25.96 A·cm−2, 26.98 A·cm−2), indicating that the cold sprayed NiCrAl coating had superior corrosion resistance. Therefore, preparing a cold sprayed NiCrAl coating is a feasible method to comprehensively improve the wear resistance and corrosion resistance of the AZ91D magnesium alloy.

Failure mechanism and acoustic emission signal characteristics of coatings under the condition of impact indentation

High Temperature Materials and Processes (2019)

Dong Tian-shun Ran Wang Guolu Li Ming Liu

Abstract In this work, the substrate, NiCr coating, Al 2 O 3 coating with NiCr undercoating and Al 2 O 3 coating were tested by an impact indentation device equipped with an acoustic emission (AE) detection equipment. The surface morphology, dimension, cross-sectional image, 3D topography of indention and bonding strength of coatings were analyzed. The failure mechanism and AE signal characteristics of the coatings under impact were studied. The results demonstrate that the failure mode of NiCr coating was dominated by interface cracking, and that of Al 2 O 3 coating is fracture and accompanied by a small amount of interface cracking, while Al 2 O 3 coating with NiCr undercoating possesses common characteristics of the first two. The energy counting and wave voltage of AE signal were more sensitive to the bonding strength of coating in the impact process, which can be used to characterize the bonding strength of coating.
