A comparison between DCCAE and conventional extrusion of Mg-9.5Li-3Al-1.6Y alloy刘军威1,彭晓东1,2,王宝1,魏国兵1,2,谢卫东1,杨艳1,刘明朴31. College of Materials Science and Engineering Chongqing University2. National...) was performed in dual-phase Mg-9.5Li-3Al-1.6Y(wt.%) alloy to develop fine-grained microstructures. The microstructure evolution during DCCAE and conventional extrusion(CE) was investigated. The microstructure......
id="ChDivSummary" name="ChDivSummary">In the present research,the dissolution mechanism of a Zr rich structure during annealing of a Ni 3 Al base alloy containing Cr,Mo,Zr and B,was investigated.The annealing treatments were performed up to 50 h at 900,1000 and 1100 C.The alloy used in this investigation was produced by vacuum-arc remelting technique.The results show that at the beginning......
">The microstructure of a Cu-Zn alloy treated under different high pressures was investigated by means of metallographic, scanning electron microscope (SEM), energy dispersive spectrometer (EDS), and X-ray diffraction (XRD), and the hardness of the Cu-Zn alloy was also measured. The results show that the α phase with a smaller grain size, different shapes, and random distribution appears in the Cu-Zn alloy......
Pitting corrosion of a Rare Earth Mg alloy GW93Yingwei Song,Dayong Shan,En-Hou HanKey Laboratory of Nuclear Materials and Safety Assessment,Institute of Metal Research,Chinese Academy of Sciences摘 要... alloys such as AZ91 are electrochemically nobler than Mg matrix, while the second phases in Rare earth(RE) Mg alloy GW93 are more active than Mg matrix. As a result, the pitting corrosion mechanism of Mg......
