properties of amorphous alloy depend upon the electron surrounding state which is dramatically impacted by supplementary elements. The soft magnetic properties of amorphous films are influenced by alloy composition, film thickness, microstructure, etc [4-5]. Since amorphous alloy phase is a thermal metastable state, heat treatment will influence the magnetic anisotropy in CoNbZr film......
. Each section discusses the thermal stability of the amorphous matrix, oxidation kinetics, and the oxide layer and amorphous substrate, which are strongly affected by internal factors(i.e., alloy...Oxidation of amorphous alloysZhiqiang Xu1,Yifei Xu1,An Zhang1,Jiangyong Wang2,Zumin Wang11.

Trans. Nonferrous Met. Soc. China 22(2012) 831-836 Crystallization microstructure of Mg65Cu25Y10 bulk amorphous alloy HUANG Kang, CHEN Gang, ZHAO Yu-tao, WANG Guo-lu, SHAO Yang School of Materials Science and Engineering, Jiangsu University, Zhenjiang 212013, China Received 22 April 2011; accepted 28 July 2011 Abstract: Mg65Cu25Y10 bulk amorphous alloy specimens prepared by conventional copper......
by the comparison of the excess free energy of the amorphous alloy and the free energy of competing crystalline states. The free energy is extrapolated from the data of three binary alloys by using Toop... that the present method can be used to predict the composition range for amorphous ternary alloys.
