A nickel-based superalloy for three-dimension (3D) printing and a powder preparation method thereof are provided. The method of preparing the nickel-based superalloy and its powder includes: RE microalloying combined with vacuum melting, degassing, refining, atomization with reasonable parameters, and a sieving process. The new method significantly reduces the cracking sensitivity of the “non-weldable” PM nickel-based superalloys, and broadens the 3D printing process window. The as-printed part has no cracks, and good mechanical properties. In addition, the powder prepared by the new method has higher sphericity and better flowability, and less irregular powders. The yield of fine powders with a particle size of 15-53 μm and medium-sized powders with a particle size of 53-106 μm that are required for 3D printing is greatly improved, which meet the requirements for 3D printing of high-quality, low-cost nickel-based superalloy powder. 1.

This invention relates to magnetocaloric materials comprising alloys useful for magnetic refrigeration applications. In some embodiments, the disclosed alloys may be Cerium, Neodymium, and/or Gadolinium based compositions that are fairly inexpensive, and in some cases exhibit only 2 nd order magnetic phase transitions near their curie temperature, thus there are limited thermal and structural hysteresis losses. This makes these compositions attractive candidates for use in magnetic refrigeration applications. Surprisingly, the performance of the disclosed materials is similar or better to many of the known expensive rare-earth based magnetocaloric materials.
