Study of the interaction of mechanochemically produced cu-in solid solutions with liquid gallium and of the structure of metallic cements on their basis

Methods of atomic-force and scanning electron microscopy and X-ray diffraction and electron microprobe analysis were used to study metallic cements formed upon the interaction of Cu-In mechanocomposites with different contents of indium. It has been established that an increase in the amount of indi...

Description
Summary:Methods of atomic-force and scanning electron microscopy and X-ray diffraction and electron microprobe analysis were used to study metallic cements formed upon the interaction of Cu-In mechanocomposites with different contents of indium. It has been established that an increase in the amount of indium in the mechanocomposite, which represents mainly a solid solution of indium in copper, leads to a decrease in the sizes of particles of the basic intermetallic compound CuGa 2 in the material obtained. After a certain induction period, indium forms a solid solution with gallium in the form of separate crystallites and nanodimensional films on the faces of CuGa 2 crystals.
