and silicate. The individual fired pellets are hardened by solid phase diffusion and the racemose sinter are consolidated by both solid phase diffusion and liquid phase bonding, the latter is 30% in sinter. Key words: chromite concentrate; pellet sintering process; wet ball milling; solid diffusion consolidation; liquid phase bonding 铬铁矿是生产铬铁合金的重要原料.但是,我国铬矿资源贫乏,保有储量仅占世界储量的0.15%,95% 铬铁矿依靠进口,进口量达302万......

="ChDivSummary">The superplastic deformation diffusion bonding of 00Cr25Ni7Mo3N duplex stainless steel was performed on a hot simulator. The microstructure of the bonding interface was characterized... to that of the base metal. In addtion, the superplastic diffusion bonding technique was not very sensitive to surface roughness levels. When the surface roughness of the bonding specimen surpassed 0.416 μm......
后沿其表面扩散;随着扩散时间的延长,Al与Sn元素间扩散和溶解程度增大,界面区无新物相生成,最终形成由Al和Sn的离异合金组织组成的界面过渡层且呈锯齿状形态分布;Al/Sn界面冶金结合是Al和Sn固相扩散,溶解与结晶共同作用的结果.关键词:Al/Sn;扩散偶;界面;扩散溶解层;形成机理Forming mechanism of diffusion couple of Al/Sn interphase diffusion solution layerMA Hui-yu, ZHU Pei-xian, ZHOU Sheng-gang, HAN Chao-hui(Faculty of Materials Science and Engineering, Kunming University of Science and Technology, Kunming 650093, China......
