An R-TM-B hot-pressed and deformed magnet (here, R represents a rare earth metal selected from the group consisting of Nd, Dy, Pr, Tb, Ho, Sm, Sc, Y, La, Ce, Pm, Eu, Gd, Er, Tm, Yb, Lu, and a combination thereof, and TM represents a transition metal) of the present invention comprises flat type anisotropic magnetized crystal grains and a nonmagnetic alloy distributed in a boundary surface between the crystal grains, and thus the magnet of the present invention has an excellent magnetic shielding effect as compared with an existing permanent magnet since the crystal gains can be completely enclosed in the nonmagnetic alloy, so that a hot-pressed and deformed magnet with enhanced coercive force can be manufactured through a more economical process.

What is disclosed is an electrode material including a sintered body containing a heat resistant element and Cr and being infiltrated with a highly conductive material. A powder mixture of a heat resistant element powder and a Cr powder is subjected to a provisional sintering in advance, thereby causing solid phase diffusion of the heat resistant element and Cr. After a Mo—Cr solid solution obtained by the provisional sintering is pulverized, the pulverized Mo—Cr solid solution powder is molded and sintered. A sintered body obtained by sintering is subjected to a HIP treatment. The highly conductive metal is disposed on the sintered body after the HIP treatment, and infiltrated into the sintered body by heating at a predetermined temperature. By conducting the HIP treatment, the withstand voltage capability and current-interrupting capability of the electrode material are improved.

A process for producing an electrode material by infiltrating a highly conductive metal such as Cu into a porous object containing heat-resistant elements. Before an infiltration step in which the highly conductive metal is infiltrated, a HIP treatment is given to a powder containing the heat-resistant elements (or to a molded object obtained by molding a powder containing the heat-resistant elements). The composition is controlled so that the HIP treatment yields a porous object which has a degree of filling of 70% or higher, more preferably 75% or higher. The highly conductive metal is infiltrated into the porous object having the controlled composition.

A method for preparing metal/metal interpenetrating phase composites is provided. The method includes forming a preform using additive manufacturing. The preform defines a materially continuous three-dimensional open-cell mesh structure. The preform includes a first metal having a melting point. The method further includes pre-heating the preform to a first temperature less than the melting point of the first metal. The method includes infiltrating the preform with a second metal in liquid form. The second metal has a melting point lower than the melting point of the first metal. The method also includes allowing the second metal to cool and form a solid matrix. The solid matrix defines a continuous material network.

Metal composites, tooling and methods of additively manufacturing these are disclosed. Metal objects and structures as provided herein are additively manufactured from metal having an infill pattern infiltrated with a second metal. Also provided herein are methods of forming such objects and structures. Methods include additively manufacturing a metal structure having an interior printed using an infill. Steps can further include infiltrating the printed infill of the structure with a liquid metal thereby forming a bi-metal composite.
