Microstructure evolution of Cu-Pb monotectic alloys during directional solidification CUI Hong-bao(崔红保), GUO Jing-jie(郭景杰), SU Yan-qing(苏彦庆), DING Hong-sheng(丁宏生), WU Shi-ping(吴士平), BI Wei-sheng..., the directional solidification microstructure changes from columnar dendrite to the irregular rod composite structure with increasing lead content and growth rate. In Cu-Pb hypermonotectic alloys, the structure......
Behavior and Mechanisms of Deformation in Intermetallic Compound Al66Mn9Ti25+La 傅云义1,刘兵1,王永欣1,陈铮1 (1.School of Materials Science and Engineering, Northwestern Polytechnical University,) Abstract:The influence of lanthanum on the microstructure, deformed behavior, microcrack susceptibility of intermetallic compound Al66Mn9Ti25 was investigated. Adding lanthanum into intermetallic compound......
. A NC surface layer consisting of the intermetallic compound FeCr was fabricated on the surface of the zirconium. The microstructure characterization of the surface layer was performed by using X-ray... with an average grain size of 25+10 nm. The deformation-induced fast diffusion of Fe and Cr from the steel shots into Zr occurred during SMAT, leading to the formation of intermetallic compound......
