| 1 | Behavior of CaO and Calcium in pure Magnesium显示文摘Mg alloys exhibit a number of good properties such as low density, good castability and high specific strength. However, molten Mg and Mg alloys are ignited without the melt protective gases during melting and casting process due to their high reactivity. The purpose of this study is to investigate effects of Ca and CaO on pure Mg through microstructure observation, ignition test and phase analysis. With increasing Ca and CaO contents, the ignition resistance of Ca or CaO added pure Mg is increased and the grains are refined. As results of XRD and EDS, CaO is reduced to Ca in CaO added pure Mg. Mg2Ca phase is formed even in 0.1 wt.%CaO added pure Mg by reduction mechanism, while Mg2Ca phase is formed over 1.35 wt.% Ca added pure Mg. | HA Seong-Ho LEE Jin-Kyu JO Hyung-Ho JUNG Seung-Boo KIM Shae K. | 2006 | Rare Metals2006，25，z2： | 7 |
| 2 | Effect of CaO addition on ignition behavior in molten AZ31 and AZ91D Magnesium alloys显示文摘Mg alloys have been widely used in automobile and electronic industries because of high specific strength, good castability, etc. However, molten Mg alloys will burn rapidly in air if not protected. To solve this problem, the molten metal should be protected from oxidation by blanketing the surface with flux or protective gases. SF6 gas is widely used for Mg alloys as a cover gas and has proved to be a successful inhibitor. However, the use of SF6 gas is limited because of its high cost and its significant impact on non-global warming potential. Therefore, SF6 gas is being replaced by alternative protection gases. Recent studies show that there has been another attempt by adding CaO into Mg alloys. The aim of this study is to evaluate the effect of CaO on the minimum amount of protective gas, which is necessary not to make ignition in the molten AZ31 and AZ91 Mg alloys. | LEE Jin-Kyu JO Hyung-Ho KIM Shae K. | 2006 | Rare Metals2006，25，z2： | 3 |

| 10 | Cr对ECO-7175铝合金热压过程中流变行为和加工图的影响显示文摘研究Cr元素对新开发的ECO-7175合金热变形行为的影响。采用Gleeble热模拟机对含Cr和不含Cr的ECO-7175样品进行热压(温度为350~500℃、应变速率为0.001~1 s^(−1)),研究合金的本构方程、加工图和显微组织演变。对变形激活能的分析表明,含Cr合金中速率控制变形机制由Al的自扩散(或Al中Mg的扩散)逐渐转变为Al中Cr的扩散,且Zener−Hollomon参数减小。对含Cr合金的加工图的分析表明,动态再结晶(DRX)区局限于高温和低应变速率下的变形,且随着应变的增加而扩大。另一方面,发现Al的自扩散(或Al中Mg的扩散)是无铬合金在所有加工条件下热变形过程中唯一的速率控制机制,其DRX区与塑性应变无关。 | Majid SEYED-SALEHI Bong Hwan KIM Seung Yoon YANG Shae Kwang KIM Ghasem EISAABADI BOZCHALOEI | 2022 | Transactions of Nonferrous Metals Society of China2022，32，5： | 1 |

| 12 | Effects of Mg Enhancement and Heat Treatment on Microstructures and Tensile Properties of Al2Ca-Added ADC12 Die Casting Alloys显示文摘The effects of Mg enhancement and heat treatment on the microstructures and tensile properties of Al_2Ca-added ADC12 die casting alloys were investigated. 0.3% and 0.5% Mg in the form of a master alloy including a trace amount of Al_2Ca were added to conventional ADC12(383 and AlSi10Cu2Fe) alloy with an initial Mg-content of 0.3% to increase the Mg content to 0.6% and 0.8%, respectively. To avoid heat treatmentinduced surface blisters, shortened solution treatment for 15 min at 490 ℃ and artificial aging for 6 h at 150 ℃ was undertaken. The results show that a 10% improvement in the shape factor of eutectic Si particles was achieved for Al_2Ca-added ADC12 with 0.8% Mg compared to the conventional ADC12 in the as-aged condition. Al_2Ca-added ADC12 with 0.8% Mg exhibited a yield strength of 289 MPa, a tensile strength of 407 MPa, and an elongation of 4.22%. | Gil-Yong Yeom Hyun Kyu Lim Shae K.Kim Soong-Keun Hyun Young-Ok Yoon | 2016 | Journal of Materials Science & Technology2016，32，10： | 1 |

| 15 | Ca对AlMg5合金均匀化过程中热压缩行为和微观结构稳定性的影响(英文)显示文摘研究微量Ca添加对AlMg5热变形过程中微观结构稳定性和动态回复行为的影响。研究手段包括扫描电子显微术(SEM)、差示扫描量热法(DSC)、电子背散射衍射(EBSD)分析和透射电子显微术(TEM)。利用JMatPro程序包对合金的凝固路径进行模拟。结果表明,Ca的加入对铸态试样的显微组织和热压缩行为没有影响,但能阻止均匀化过程中晶粒的急剧长大。在热压缩过程中,无Ca合金中的粗晶粒促进合金的动态回复,减缓动态再结晶,其再结晶晶粒的主要形核机制是粒子激发形核。另一方面,热压缩含Ca合金的显微组织受到Al4Ca金属间化合物的显著影响。通过JMatPro预测,并通过DSC、SEM和TEM揭示Al4Ca相的形成。最后,在含Ca合金的晶界处发现Al4Ca析出相通过Zener钉扎效应阻碍α(Al)相的增长,提高均匀化过程中微观结构的稳定性。 | Bong Huang KIM Majid SEYED SALEHI Ashkan NOURI Mohammad Sadegh MOHEBI Seong Ho HA Young Ok YOON Hyun Kyu LIM Shae KKIM BGhasem EISAABADI | 2020 | Transactions of Nonferrous Metals Society of China2020，30，3： | 1 |
