| Abstract: | Sb Se and Ge Sb Te series alloys were prepared by melting method according to the composition. Their microstructure and structure were investigated. The result showed that the microstructure of alloys was homogeneous. The X ray diffraction result showed that the Sb and the Se precipitated from the specimens 1 # and the specimens 2 # of Sb Se series alloy respectively, while the specimens 3 # in the stoichiometric compositions of Sb Se series alloys appeared the eutectic Sb 2Se 3 entirely. The Sb precipitated from the specimens 5 # of Ge Sb Te series alloys, while the specimens 4 # in the stoichiometric compositions of Ge Sb Te series alloys appeared the eutectic GeSb 2Te 4 entirely. |
