Fabrication of Mg-Zn-Y-based quasi-crystal by pouring melt into different cooling media被引量:2
《China Foundry》2012年第3期207-214,共8页Wang Zhifeng Zhao Weimin Qin Chunling Hur Bo-Young 
supported by Natural Science Foundation of Hebei Province, China (E2010000057, E2010000121, E2012202017);International S & T Cooperation Program of China (2010DFA51850)
Mg-Zn-Y-based quasi-crystal (QC) alloys were fabricated by pouring melts into different cooling media. The effects of different cooling rates on the QC morphology, size, volume fraction and micro-hardness were studi...

ABOUT TWO TYPES OF MICROSTRUCTURES ADAPTED TO HEAT EVACUATION AND ELASTIC STRESS:SNOW FLAKES AND QUASI-CRYSTALS
《Acta Mathematica Scientia》2012年第1期84-108,共25页Luc Tartar 
supported by ONR Grant N000140910301
I first met Constantine Dafermos in August 1974, at a meeting at Brown University, where I was invited because my former advisor (Jacques-Louis LIONS) could not come, and he had proposed my name. I was happily surpr...
