  How the tin concentration affects the interactions of intermetallic compounds of the Cu-Sn system with liquid gallium and a gallium-tin eutectic

  摘要：

  Interactions in the copper-gallium-tin ternary system are studied. New phase formation involves the step of dissolution of solid copper alloys in a liquid phase. The induction period of tin segregation in an autonomous phase depends on tin concentration in the feed. The formation of solid solution of gallium in tin is suggested.

  Single crystals of Ta7Cu10Ga34 were grown from the elements in a Cu/Ga melt. Ta7Cu10Ga34 represents the first ternary compound of the system Ta/Cu/Ga. The crystal structure (Cmmm, oC102, Z = 2, a = 23.803(1), b = 12.2087(4), c = 5.7487(2) A, 1291 refl. 78 parameters, R1 = 0.037, wR2 = 0.070). The crystal structure is characterized by rods of pentagonal prisms MGa10, which are alternatingly occupied

  日期：2011.4

  The standard enthalpies of formation of some shape memory alloys have been measured by high temperature direct synthesis calorimetry at 1373 K. The following results (in kJ/mol of atoms) are reported: CoCr (-0.3 +/- 2.9); CuMn (-3.7 +/- 3.2); Cu3Sn (-10.4 +/- 3.1); Fe2Tb (-5.5 +/- 2.4); Fe2Dy (-1.6 +/- 2.9); Fe17Tb2 (-2.1 +/- 3.1); Fe17Dy2 (-5.3 +/- 1.7); FePd3 (-16.0 +/- 2.7); FePt (-23.0 +/- 1.9); FePt3 (-20.7 +/- 2.3); NiMn (-24.9 +/- 2.6); TiNi (-32.7 +/- 1.0); TiPd (-60.3 +/- 2.5). The results are compared with some earlier experimental values obtained by calorimetry and by EMF technique. They are also compared with predicted values on the basis of the semi empirical model of Miedema and co-workers and with ab initio calculations when available. We will also assess the available information regarding the structures of these alloys. (C) 2011 Elsevier B.V. All rights reserved.

• Chemical interaction of Cu-In, Cu-Sn, and Cu-Bi solid solutions with liquid Ga-In and Ga-Sn eutectics

  The reactions of copper-based Cu-In, Cu-Sn, and Cu-Bi solid solutions with liquid Ga-In and Ga-Sn eutectics have been studied in situ by synchrotron x-ray diffraction. The results indicate that the dynamics of the process and the phase composition, grain size, and microstructure of the resulting materials depend on the components of the solid solution and eutectic.
