摘要
Abstract
The micro-structural evolution in Mo-Cu alloy has been investigated by scanning electron microscopy (SEM) and transmission electron microscopy (TEM). Mo-Cu alloy was made through liquidphase sintering of powders of Mo and Cu milled by mechanical activation,which is used for heat dissipation in high performance microelectronic circuits. The micro-structural characterization of Mo-Cu alloy is homogeneous compound structure of adhesive phase Cu linked with Mo grains. Mo grains frequently string together. There is little ellipsoidal Mo grains singly existed around by Cu phase. Between Mo grains and Cu zone,there is a medium changing zone,a width of 10～20nm. Its thermal expansivity and other properties are also presented and discussed.关键词
