alloys. However, Mg-Li binary alloy has relatively poor mechanical properties[5]. To overcome this shortcoming, alloying is an effective strengthening method. Al is one of the most effective elements for Mg-Li alloy strengthening. Accordingly, it is the most commonly used alloying element in Mg-Li alloys. However, when the Al content is larger than 6% (mass fraction), the strengthening effect......
The Strengthening of Cu-15Ni-8Sn Alloy WANG Ming-Pu1,WANG Yan-hui1,HONG Bin1 (1.School of Material Science and Engineering, Central South University, Changsha China) 摘要:The microstructure, property and relation between them of Cu-15Ni-8Sn alloy are studied by means of TEM and the measurement of hardness. The results show that γ '' metastable phase strengthens alloy because of its ordering......
Microstructure, mechanical properties and age-hardening of Mg-Li alloy sheets LI Hong-bin(李红斌), YAO Guang-chun(姚广春), GUO Zhi-qiang(郭志强), LIU Yi-han(刘宜汉), JI Hai-bin(吉海宾) School of Materials... alloys from a practical point of view. In this paper Mg-Li-Zn alloy was studied systematically. Firstly, the thin sheets of the Mg-(5-22)Li-2Zn alloys with thickness of 0.5-2 mm were produced at room......
in order to reduce mass[1]. However, Mg-Li alloy is chemically active, and its cast ingot is generally prepared by common mould casting because of no usable semi-continuous casting technique and equipment. So, Mg-Li alloy ingot has larger grain size and its strength is obviously lower than those of general magnesium alloys. To improve its strength and then extend its application, many new processes......
