Liquid reaction medium ball milling technique is to be milled directly to the liquid metal, at a certain temperature range, ball, and the tube wall to bare metal and a solid phase reaction liquid intermetallic compound powder is a powder preparation technique. The main contents of this paper was prepared by solid-liquid reaction milling technology department and Mo Cu intermetallic compound. Product by X-ray diffraction (XRD), scanning electron microscopy (SEM) and transmission electron microscopy (TEM) analysis of the product characteristics and other methods. In this thesis, Cu-Sn, Cu-Zn, Cu-Ni-Sn, Mo-Sb and Mo-Sn alloys for the milling of the reaction liquid, the ball feed ratio of 20:1, ball speed is 80r/min. And using planetary mill, a ball with the same feed ratio, respectively Cu-Sn, Cu-Ni-Sn and Mo-Sb alloys three mechanical alloying for a comparative experiment. Results of this experiment are as follows: (1) The Cu-Sn-based, obtained at 573K the ball 6h Cu6Sn5 intermetallic compound phase and Sn mixed powder; ball milled at 673K ??12h, to obtain a mixed powder of Cu6Sn5 and Cu3Sn; ball milled at 773K 6h get Cu3Sn intermetallic phase powder with milling time, no other new phase generator; For the Cu-Zn system at 723K, respectively milling 4h, 8h and 12h after averaging a certain content of Cu5Zn8 phase; For the Cu- Ni-Sn ternary system, the use of the Cu-Sn binary system by adding Ni elemental powders as well as Cu and Ni ball milled pure Sn solution in two ways, at 573K under milling 12h and 24h are generated binary metal intermetallic compounds Cu6Sn5 . SEM and TEM results show that the resulting intermetallic compound powder particles are about 100nm, and Ni powder is helpful to Cu6Sn5 fine and homogeneous formation of nanoparticles. (2) For the Mo-Sn-based, at 573K using Mo ball milling the liquid 6h been MoSn2 pure Sn intermetallic compound, the reaction time, the milled product is MoSn2, but the relative content increased; the Mo-Sb system, the 6h 993K quickly Mo3Sb7 ball milled powder, milling to 36h, Sb fluid exhausted from the ball to get Mo3Sb7 and flaking of the large amount of unreacted Mo. SEM and TEM results show that the resulting intermetallic compound powder particles reach about 200nm. (3) Cu-Sn system were prepared by mechanical alloying process Cu6Sn5 temperature phase; in the Cu-Ni-Sn system mechanical alloying process, Sn and Ni elements of diffraction peaks after 20h of mechanical alloying all disappear, Cu's diffraction peak broadening; Mo-Sb system during prolonged mechanical alloying process were not found to generate intermetallic phases, but the response to 50h, Mo and Sb in both width of the diffraction peak and peak intensity decreased Sb . According to the above results, combined with the liquid metal on the solid pure metal and the role of mechanical forces on the solid, the paper discusses the solid-liquid reaction milling of intermetallic compounds and solid-liquid reaction mechanism of the process of solid-liquid reaction milling process and models. Finally, this paper also compares the solid-liquid reaction milling and mechanical alloying difference between the two technologies.
