摘要： A method is provided for the heat treatment of an object comprising at least one rare-earth element with a high vapor pressure. One or more objects comprising at least one rare-earth element with a high vapor pressure are arranged in an interior of a package. An external source of the at least one rare-earth element is arranged so as to compensate for the evaporation of this same rare-earth element from the object and/or to increase the vapor pressure of the rare-earth element in the interior of the package, and the package is heat treated.

摘要： A method is provided in which a lower box comprising a base, walls that surround the base and an open side, and an upper box comprising a cover, walls that surround the cover and an open side are provided. One or more objects are arranged on the base of the lower box. The object(s) are covered with the upper box such that the open side of the upper is oriented towards the base of the box, the walls of the upper box are arranged on the base of the lower box and a gap is formed between the walls of the upper box and the walls of the lower box. A powder material is introduced into the gap in order to form an assembly having an interior. The powder material provides a mechanical obstacle to gas exchange between the interior and the environment. This assembly is then heat treated.

摘要： A sintered magnet body (RaT1bMcBd) coated with a powder mixture of an intermetallic compound (R1iM1j, R1xT2yM1z, R1iM1jHk), alloy (M1dM2e) or metal (M1) powder and a rare earth (R2) oxide is diffusion treated. The R2 oxide is partially reduced during the diffusion treatment, so a significant amount of R2 can be introduced near interfaces of primary phase grains within the magnet through the passages in the form of grain boundaries. The coercive force is increased while minimizing a decline of remanence.

摘要： Disclosed are a nickel-based superalloy formed by selective laser melting and a preparation method thereof, belonging to the technical field of an additive manufacturing from metal powder. In the disclosure, CrFeNb alloy powder is used as a grain refiner, and its element composition is within the composition range of a nickel-based superalloy powder to ensure that the prepared nickel-based superalloy has the same element composition with the original alloy; the grain size in the nickel-based superalloy could be refined by the addition of CrFeNb alloy powder, such that the anisotropic columnar grain structure in the alloy is transformed to equiaxed grain structure, thereby improving mechanical properties of the alloy. The results of the examples show that the nickel-based superalloy prepared in the disclosure exhibits a yield strength of not less than 710 MPa at room temperature, a tensile strength of not less than 1010 MPa, an elongation of not less than 19%, and a hardness of not less than 330 HV; after the heat treatment, the nickel-based superalloy exhibits a yield strength of not less than 1400 MPa, a tensile strength of not less than 1100 MPa, an elongation of not less than 5.09%, and a hardness of not less than 530 HV.
