科学网—《自然—材料学》:美国研制出迄今强韧度最好合金

说 大块非晶 金属玻璃老百姓看不懂,这么翻译挺好的.呵呵2011-1-11 23:09:32 匿名 引用:“引用:“引用:“2011-01-11 09:57:54 AMCQ Sun said:E[3] Liu XJ, Yang LW, Zhou ZF, Sun CQ, Inverse Hall-Petch relationship of nanostructured TiO2: Skin-depth energy pinning versus surface preferential melting, J APPL PHYS 108, 073503 (2010).2011-1-11 23:08:17 匿名 引用:“引用:“2011-01-11 09:57:54 AMCQ Sun said:E-mail: ecqsun@ntu.edu.sgWeblink: http://www3.ntu.edu.sg/home/ecqsun[1] Sun CQ, et al., Interface quantum trap depression and charge polarization in the CuPd and AgPd bimetallic alloy catalysts, Phys.

On the other hand, huge amount of defects creation s associated with high proportion of undercoordinated atoms that induce local bond contraction and strength gain, which cause local densification and entrapment of charge and energy, initiating the competition between the thermal stability and mechanical strength.3. welcome for discussion.2011-1-11 23:05:12 匿名 2011-01-11 09:57:54 AMCQ Sun said:1. A recent XPS investigation revealed that the 3d levels of Ag and Pd shift up but the Cu 2p and Pd 3d shift down upon Ag/Pd and Cu/Pd alloying. The valence bands of Ag/Pd and Cu/Pd shift in the same direction as the core levels do. The downshift is attributed to the interface quantum entrapment and the upward shift of AgPd to the interface polarization.目前已有11条评论
