The Al11Cr4 Phase is confirmed, and is stable in the 600 °C isothermal section; its decomposition temperature is between 690 °C and 800 °C. The solubility of Sn in Al–Cr binary compounds is negligible. Six intermediate phases, i.e., Al7Cr, Al11Cr2, Al4Cr, Al11Cr4, Al8Cr5 ...
结果证明了分子筛中27Al化学位移峰位置主要取决于三个因素:骨架的拓扑结构、骨架外阳离子的类型和阳离子的水合程度。基于简单模型的静态计算结果会导致对 NMR 谱中峰位置,Al 分布甚至谱峰数量解释的定性错误。因此,在27Al化学位移计算中采用 ope...
相对于新手村的轻松惬意和偶遇强者的短暂挫败,面对FPX的失利是AL的当头棒喝。从开赛时颓势难掩到Summit加入后强势归来,FPX无疑是AL季后赛名额的头号竞争对手,所以败给FPX让AL的晋级形势更加艰难。更重要的是,重组归来并且短暂磨合的前世界冠军,仍然能...
The 600 and 800°C isothermal sections of the Al-Ni-Sn ternary system were determined based on examination of equilibrated alloys by SEM spectroscopy and x-ray powder diffraction. Nine and Six three-phase regions exist in the Al-Ni-Sn system at 600 and 800°C respectively. All the Al-Ni...
The low-temperature phase Mn3Sn2 was observed at 450 degrees C. The solubility of Al in Mn3Sn, Mn3Sn2, MnSn2 and that of Sn in Al8Mn5 at 450 degrees C is about 3.1, 2.9, 0.6, and 1.7 at.%, respectively. The high-temperature phase Mn2-xSn was observed at 800 degrees C. ...
Thin foils of the double solid solution (Zr0.5,Ti0.5)2(Al0.5,Sn0.5)C MAX phase were in situ irradiated in a transmission electron microscope (TEM) up to a fluence of 1.3×10 ionscm (7.5 dpa), using 6 keV He ions. Irradiations were performed in the 350-800 °C temperature range. ...
The high-temperature phase Mn2-xSn was observed at 800?°C. The solubility of Al in Mn3Sn, Mn2?xSn and that of Sn in Al8Mn5 at 800?°C was measured to be 2.8, 3.6 and 1.0?at.%, respectively. Al12Mn, also named G phase, was proved to be stable at 450?°C....
elliptic shape or roundish shape in the tip are dispersed and precipitated into an Al matrix 1 strengthened by Cr, etc., Sn-Pb alloy grains 3 are precipitated adjacently to the Si grains 2 and a part 3a thereof is converted into a liquid phase, by which the Al-Sn-Pb bearing alloy ha...
Mohammed·Al·Ameri(出生于1959年-)是一位著名的当代视觉艺术家,他的灵感主要来自上世纪70年代。20世纪70年代是艺术巩固和进步的时期,通常被定义为对过去十年的主要紧张局势的回应。概念艺术作为一场有影响力的运动出现,是极简主义的部分演变和回应。 加微信uhuayuan4,领...
2022AL规范化诊疗巡讲会-南昌站 七月流火,炎夏的热浪也不能阻挡江西省血液病工作者学习医学知识的热情,2022年7月3日,2022急性白血病规范化诊疗巡讲会-第十九站南昌站学术会议在南昌顺利举行。会议由江西省人民医院血液内科主任金成豪教授,南昌大学一附院血液...
