| 1 | Effect of Y addition on microstructure and corrosion behavior of extruded Mg-Zn-Nd-Zr alloy显示文摘In this study,the effect of Y addition(0,0.5,1 and 2 wt%)on microstructure and corrosion properties of Mg-6Zn-0.5Zr-1 Nd(wt%)alloy was investigated.The alloys were produced by low-pressure die casting method and extruded at 300℃and 400℃after homogenization treatment at 400℃for 24 h.The results showed that the as-cast microstructure of the alloy with no Y addition consisted ofα-Mg,Mg-Zn binary and Mg-Zn-Nd ternary phases.With increasing Y additions,the average grain size showed a substantial decrease and two kinds of ternary Mg-Zn-Y ternary phases,designated as I-phase(Mg3Zn6Y)and W-phase(Mg3Zn3Y2)were formed.Homogenization treatment resulted in a partial dissolution of second phase particles.Extrusion process gave rise to a remarkable grain refinement due to the DRX mechanism.The extruded alloys with no Y addition exhibited poor corrosion resistance due to the strong micro galvanic coupling effect.Y additions up to 1 wt%improved the corrosion resistance due to the formation of finer grains,fine and uniform distribution of second phase particles and more stable oxide film. | Huseyin Zengin Yunus Turen | 2020 | Journal of Magnesium and Alloys2020，8，3： | 11 |
| 2 | 添加锡对AS21镁合金显微组织和耐腐蚀性能的影响(英文)显示文摘研究添加锡对AS21 镁合金显微组织和耐腐蚀性能的影响。采用低压压铸法制备分别添加0、0.5、1 和2 wt.% Sn 的AS21 合金。用光学显微镜和扫描电镜进行显微组织表征,通过在3.5% NaCl 溶液中浸渍和电化学腐蚀试验研究合金的耐腐蚀性能。微观检测结果显示,AS21 合金中含有α-Mg、孤立的β-Mg17Al12 和汉字状Mg2Si 金属间化合物相。随着Sn 含量的增加,Mg2Si 相的分布变得更加离散和致密。当Sn 添加量为2 wt.%时,形成遍布于整个组织的富Sn 网状结构,汉字状组织由短棒状的Mg2Si 相排列组成。持续浸泡腐蚀试验表明,随着锡含量的增加,AS21 合金的降解程度不断降低,当锡含量为2 wt.%时,AS21 合金的腐蚀速率降低约65%。电化学腐蚀试验也表明,随着锡含量的增加,AS21 合金的耐蚀性逐渐提高。 | Huseyin ZENGIN Yunus TUREN Hayrettin AHLATCI Yavuz SUN Abdullah Cahit KARAOGLANLI | 2019 | Transactions of Nonferrous Metals Society of China2019，29，7： | 4 |
| 3 | Microstructure,mechanical properties and corrosion resistance of as-cast and as-extruded Mg-4Zn-1La magnesium alloy显示文摘Microstructure,mechanical properties and corrosion resistance of as-cast and as-extruded Mg-4 wt%Zn-1 wt%La magnesium alloys were investigated.The alloys were produced by low-pressure die casting method and extruded at 350℃after homogenization at 400℃for 24 h.The results show that the as-cast alloy mainly consists of primaryα-Mg matrix and Mg-Zn-La ternary second phases(also called T-Phase)along grain boundaries and isolated spherical particles inside the grains.After extrusion at350℃,the average grain size decreases by 81%due to dynamic recrystallization mechanism and T-phase particles are distributed along the extrusion direction.The elongation,yield strength and tensile strength of the as-cast Mg-4Zn-1La alloy increase by 179%,90%and 40%,respectively,as a result of the extrusion process.The as-extruded Mg-4Zn-1La alloy shows better corrosion resistance than the as-cast alloy due to increased grain boundaries and decreased content of T-phase. | Huseyin Zengin Yunus Turen Hayrettin Ahlatci Yavuz Sun | 2020 | Rare Metals2020，39，8： | 4 |

| 5 | Evolution of Microstructure, Residual Stress, and Tensile Properties of Mg–Zn–Y–La–Zr Magnesium Alloy Processed by Extrusion显示文摘The microstructure, texture, residual stress, and tensile properties of Mg–6 Zn–2 Y–1 La–0.5 Zr(wt%) magnesium alloy were investigated before and after extrusion process, which performed at 300 °C and 400 °C. The microstructural characterizations indicated that the as-cast alloy was comprised of α-Mg, Mg–Zn, Mg–Zn–La, and Mg–Zn–Y phases. During homogenization at 400 °C for 24 h, most of the secondary phases exhibited partial dissolution. Extrusion process led to a remarkable grain refi nement due to dynamic recrystallization(DRX). The degree of DRX and the DRXed grain size increased with increasing extrusion temperature. The homogenized alloy did not show a preferential crystallographic orientation, whereas the extruded alloys showed strong basal texture. The extrusion process led to a signifi cant improvement on the compressive residual stress and mechanical properties. The alloy extruded at 300 °C exhibited the highest basal texture intensity, the compressive residual stress and hardness, and yield and tensile strengths among the studied alloys. | Huseyin Zengin Yunus Turen Muhammet Emre Turan Fatih Ayd?n | 2019 | Acta Metallurgica Sinica(English Letters)2019，32，11： | 2 |
