| 1 | Anisotropy of the crystallographic orientation and corrosion performance of high-strength AZ80 Mg alloy显示文摘A high-strength AZ80 Mg alloy was prepared through multi-direction forging,thermal extrusion,and peak-aged heat treatment.The microstructure,crystallographic orientation and corrosion performance of extrusion-direction,transverse-direction,and normal-direction specimens were investigated using scanning electron microscopy,electron backscatter diffraction,and atomic force microscopy,respectively.Experimental results showed that crystallographic orientation significantly influenced the corrosion performance of AZ80 Mg alloy.Corrosion rates largely increased with decreased(0001)crystallographic plane intensity,whereas the(10−10)and(2−1−10)crystallographic plane intensities increased.This study showed that the corrosion rates of alloy can be modified to some extent by controlling texture,thereby promoting the applications of high-strength AZ80 Mg alloys in the aerospace and national-defense fields. | Quantong Jiang Xiumin Ma Kui Zhang Yantao Li Xinggang Li Yongjun Li Minglong Ma Baorong Hou | 2015 | Journal of Magnesium and Alloys2015，3，4： | 5 |
| 2 | Enhanced photoelectrochemical cathodic protection performance of MoS_(2)/TiO_(2)nanocomposites for 304 stainless steel under visible light显示文摘In this work,TiO_(2)nanotube arrays(NTAs)sensitized with MoS_(2)microspheres(MoS_(2)/TiO_(2)nanocomposites)were prepared on a flat Ti substrate via two-step anodization and hydrothermal method sequentially.TiO_(2)NTAs were composed of many orderly nanotubes,whose large specific surface area was favorable for light absorption and MoS_(2)microsphere adhesion.The MoS_(2)microsphere as a narrow band gap semiconductor extended the TiO_(2)NTAs’absorption band edge to the visible region.The 2D structure of MoS_(2)microspheres and the construction of heterojunction electronic field at the interface of MoS_(2)microspheres and TiO_(2)NTAs promoted the separation of photoinduced carriers.The MoS_(2)/TiO_(2)nanocomposites could provide higher photoelectrochemical cathodic protection for 304 stainless steel(304 SS)under visible light than pristine TiO_(2)NTAs. | Xiumin Ma Zheng Ma Dongzhu Lu Quantong Jiang Leilei Li Tong Liao Baorong Hou | 2021 | Journal of Materials Science & Technology2021，，5： | 5 |
| 3 | Corrosion behavior of Mg-8Li-3Zn-Al alloy in neutral 3.5%NaCl solution显示文摘The corrosion behavior of Mg-8Li-3Zn-Al alloy was investigated in neutral 3.5%NaCl aqueous solution by morphology observation and electrochemical tests.The weight loss method was to measure the corrosion rate.The electrochemical results indicated that the corrosion resistance of Mg-8Li-3Zn-Al alloy in 3.5%NaCl solution is poorer than that in distilled water.The Cl-anion leads to the initiation and development of the corrosion pits.And the corrosion products are mainly Mg(OH)_(2). | Lihui Yang Quantong Jiang Meng Zheng Baorong Hou Yantao Li | 2016 | Journal of Magnesium and Alloys2016，4，1： | 4 |
| 4 | Long non-coding RNA LINC-PINT attenuates paclitaxel resistance in triple-negative breast cancer cells via targeting the RNA-binding protein NONO显示文摘The treatment of triple-negative breast cancer(TNBC)relies largely on chemotherapies.However,it is frequent that TNBC patients develop resistance to the chemotherapy drugs.Generation of drug-resistant cell lines facilitates the identification of drug resistance.Here,we established two paclitaxel(PTX)-resistant TNBC cancer cell lines using an intermittent and stepwise method and found that long non-coding RNA long intergenic non-protein-coding RNA p53-induced transcript(LINC-PINT)was significantly decreased in PTX-resistant cancer cells.Ectopic expression of LINC-PINT sensitized both PTX-resistant TNBC and wild-type TNBC to PTX.Moreover,RNA immunoprecipitation showed that LINC-PINT bound to RNA-binding protein NONO.Overexpression of LINC-PINT resulted in the degradation of NONO in a proteasome-dependent manner and vice versa.Knockdown of NONO with siRNA sensitized TNBC to PTX.We further analyzed the expression level of LINC-PINT and NONO in patient samples via online database and found that LINC-PINT and NONO may function antagonistically in all types of breast cancers.Taken together,our data illustrated a tumor suppressor role of LINC-PINT in sensitizing TNBC to chemotherapies via destabilizing NONO. | Jinghua Chen Meiqin Zhu Liqiu Zou Junxian Xia Jiacheng Huang Quantong Deng Ruilian Xu | 2020 | Acta Biochimica et Biophysica Sinica2020，52，8： | 4 |
| 5 | The corrosion behavior of Mg-Nd binary alloys in the harsh marine environment显示文摘The corrosion behavior of Mg-Nd binary alloys in the harsh South China Sea environment was researched by scanning electron microscopy,energy-dispersive spectrometry and X-ray diffraction analysis.In order to explain the corrosion mechanism,corrosion resistance was analyzed by weight loss rate and electrochemical measurement in the laboratory.With a continuous enlargement of Nd-content,Mg 12 Nd phases increased and multiplied.The weight loss rate of Mg-0.5Nd alloy was 0.0436 mg·cm^(-2)·y^(-1)(0.0837 mm·y^(-1)),whereas that of Mg-1.5Nd alloy was 0.0294 mg·cm^(-2)·y^(-1)(0.0517 mm·y^(-1))during the exposure corrosion in the South China Sea site.The mechanical strength of Mg-1.5Nd alloy was 148 MPa before the exposure in the harsh marine environment,while the residual mechanical strength was merely about 94 MPa after the exposure test.Both Mg-1.5Nd alloy and Mg-1.0Nd alloy occurred the brittle fracture,which resulted that the elongation was nearly equal to zero.The self-corrosion current density demonstrated that degradation rate of Mg-Nd binary alloys was as follows:Mg-0.5Nd>Mg-1.0Nd>Mg-1.5Nd.For the South China Sea corrosion site,a large amount of sea salts exited in the atmospheric environment.Due to the heavy rainfall and high humidity,sodium chloride in the atmospheric environment dissolved,more serious electrochemical corrosion occurred on the surface of Mg-Nd binary alloys. | Quantong Jiang Dongzhu Lu Ning Wang Xiutong Wang Jie Zhang Jizhou Duan Baorong Hou | 2021 | Journal of Magnesium and Alloys2021，9，1： | 3 |
| 6 | The corrosion behaviors of Mg-7Gd-5Y-1Nd-0.5Zr alloy under(NH4)_(2)SO_(4),NaCl and Ca(NO_(3))_(2)salts spray condition显示文摘The corrosion behaviors of Mg–7Gd–5Y–1Nd–0.5Zr alloys after T5 treatment under(NH4)_(2)SO_(4),NaCl and Ca(NO_(3))_(2)salt spray condition were investigated by weight loss rates,residual mechanical properties,scanning electron microscope(SEM),X-ray Diffraction(XRD)and potentiodynamic polarization tests.The corrosion degree of Mg–7Gd–5Y–1Nd–0.5Zr alloys in Ca(NO_(3))_(2)salt spray was very shallow by corrosion morphology and the corrosion route was extended along the surface in texture-like shape,while the alloy in NaCl and(NH4)_(2)SO_(4)salt spray were major local corrosion and there were serious corrosion pits on the surface.The weight loss rates in(NH4)_(2)SO_(4),NaCl and Ca(NO_(3))_(2)salt spray was respectively 0.4147,0.1618 and 0.0725 mg/(cm2 d−1).The results of residual mechanical properties indicated that the corrosion order in salts spray of Mg–7Gd–5Y–1Nd–0.5Zr alloys is NH4SO4>NaCl>Ca(NO_(3))_(2),which was consistent with the results of potentiodynamic polarization tests.The type of the salts will play a vital role in the initiation of the corrosion of EW75 alloy when they are used in the atmosphere environments.Inorganic salts with the smaller PH value after dissolution will have a stronger impact on the corrosion of EW75 magnesium alloys. | Quantong Jiang Kui Zhang Xinggang Li Yongjun Li Minglong Ma Guoliang Shi Jiawei Yuan | 2013 | Journal of Magnesium and Alloys2013，1，3： | 2 |
| 7 | The corrosion behavior and mechanical property of the Mg-7Y-x Nd ternary alloys显示文摘The corrosion behavior and mechanical property of Mg-7Y-x Nd(x=0.5,1.0,1.5 wt%)alloys were investigated.The microstructure and precipitations of Mg-7Y-x Nd alloys were studied by scanning electron microscopy,energy-dispersive spectrometry and X-ray Diffraction.The quantities of the Mg_(12)(Y,Nd)phase increased,whereas that of the Mg_(24)(Y,Nd)_(5)phase decreased with increasing Nd-content.The weight loss rate decreased from 17.5020 mg cm^(-2)·d^(-1)(36.7542 mm y^(-1))to 9.3744 mg cm^(-2)·d^(-1)(19.6862 mm y^(-1)).The electrochemical measurement also demonstrated the similar tendency.The loss in mechanical properties after corrosion reaction followed the order Mg-7Y-0.5Nd>Mg-7Y-1.0Nd>Mg-7Y-1.5Nd.The precipitations played dual roles in the corrosion resistance that depended on type and distribution. | Quantong Jiang Xianzi Lv Dongzhu Lu Jie Zhang Baorong Hou | 2018 | Journal of Magnesium and Alloys2018，6，4： | 2 |
| 8 | Microstructure and properties of nitrided layer of titanium plate,produced by simultaneous laser quenching and liquid-nitrogen cryogenics显示文摘In the present study, titanium plate was treated by a novel method of laser quenching, simultaneously combined with liquidnitrogen cryogenics(LQLNC). The microstructure and properties of the titanium plate after treatment were investigated by X-ray diffraction, scanning electron microscopy, energy dispersive spectrometry, Vickers hardness testing, and friction wear testing.The results show that the treated titanium plate is covered by a nitrided layer with a homogeneous thickness of about 60 μm,while the nitrided layer consists of Ti N and α-Ti phases. Compared to general laser quenching, the LQLNC treatment increases the hardness and wear resistance of the surface-modified layer of the titanium plate. As a result of grain refinement in the nitrided layer, the cracking induced by the rapid solidification of the conventional laser-quenching process has also been effectively solved. | YAO QuanTong TIAN Chen SUN Jian ZUO Liang TONG WeiPing | 2018 | Science China(Technological Sciences)2018，61，12： | 1 |

| 10 | The corrosion characteristic and mechanism of Mg-5Y-1.5Nd-xZn-0.5Zr(x=0,2,4,6 wt.%)alloys in marine atmospheric environment显示文摘The microstructure and precipitated phases of as-cast Mg-5Y-1.5Nd-x Zn-0.5Zr(x=0,2,4,6 wt.%)alloys were investigated by optical microscopy,scanning electron microscopy,energy-dispersive spectrometry and X-ray Diffraction.The exposure corrosion experiment of these magnesium alloys was tested in South China Sea and KEXUE vessel atmospheric environment.The corrosion characteristic and mechanism of magnesium alloys of Mg-5Y-1.5Nd-x Zn-0.5Zr(x=0,2,4,6 wt.%)alloys were analyzed by weight loss rate,corrosion depth,corrosion products and corrosion morphologies.The electrochemical corrosion tests were also measured in the natural seawater.The comprehensive results showed that Mg-5Y-1.5Nd-4Zn-0.5Zr magnesium alloy existed the best corrosion resistance whether in the marine atmospheric environment and natural seawater environment.That depended on the microstructure,type and distribution of precipitated phases in Mg-5Y-1.5Nd-4Zn-0.5Zr magnesium alloy.Sufficient quantity anodic precipitated phases in the microstructure of Mg-5Y-1.5Nd-4Zn-0.5Zr alloy played the key role in the corrosion resistance. | Quantong Jiang Dongzhu Lu Liren Cheng Nazhen Liu Baorong Hou | 2024 | Journal of Magnesium and Alloys2024，12，1： | 0 |
