    Abstract: An R-T-B rare earth sintered magnet contains R which represents a rare earth element; T which represents a transition metal essentially containing Fe; a metal element M which represents Al and/or Ga; B; Cu; and inevitable impurities the R-T-B rare earth sintered magnet including 13.4 to 17 at % of R, 4.5 to 5.5 at % of B, and 0.1 to 2.0 at % of M, and T as the balance; in which the R-T-B rare earth sintered magnet is formed of a sintered body which includes a main phase composed of R2Fe14B and a grain boundary phase including a larger amount of R than the main phase; in which the magnetization direction of the main phase is a c-axis direction, in which crystal grains of the main phase have one of an elliptical shape and an oval shape extended in such a direction so as to cross the c-axis direction; and in which the grain boundary phase includes an R-rich phase in which the total atomic concentration of the rare earth elements is 70 at % or greater and a transition metal-rich phase in which the total atomic concentration of the rare earth elements is 25 to 35 at %.

    Abstract: A cold spray system includes a powder generator and a powder feeder. The powder generator has a powder source disposed within a housing. The powder feeder is in fluid communication with the housing and the powder generator within the housing. A closed circuit defined from the powder generator to the powder feeder conveys powder from the powder generator to the powder feeder without exposing the powder to contaminates from outside the closed circuit.
