The invention discloses a modified material capable of being used for a water-absorbing powder material without agglomeration after long-term storage and a preparation process of the modified material. The preparation process comprises the following steps: S1, preparing a modifier, namely preparing the required modifier from a component A, an industrial additive and fumed silica according to a weight part ratio; s2, pretreatment and feeding; s3, synchronous grinding and modification, wherein the premix is put into ultrafine crushing equipment to be processed; s4, under the action of mechanism and mechanical force, the component A in the modifier and fumed silica synchronously complete spreading adsorption and nanometer isolation inlaying on the particle new surface; and S5, collecting and post-processing. According to the invention, the modifier is added to modify the surface of the powder while the particles are crushed, so that the surface modification of the fine oxidant is more uniform, and the particles meeting the particle size requirement are directly used as usable products according to the dispersing performance and the flowing performance of the powder in the grinder; and the problem of mutual adhesion of particles is solved.

The invention provides a laser powder bed melting (LPBF) Mar-M247 alloy forming method for reducing cost, and belongs to the technical field of metal additive manufacturing. The method aims at solving the technical problems that in the prior art, when Mar-M247 alloy is formed, a process window is narrow, and cracks and air holes are likely to be generated. The method comprises the steps that a substrate used for forming is preheated, and the temperature of the substrate is made to reach 120 DEG C to 150 DEG C; under the protection of inert atmosphere, Mar-M247 alloy powder is laid on the substrate layer by layer; and laser scanning is carried out on the alloy powder by cooperatively regulating and controlling the laser power, the scanning speed and the scanning interval, so that the energy density in the forming process is 55.28 J / mm < 3 >-73.2 J / mm < 3 >. According to the method, through combination of base plate preheating and precise energy density control, cracks and air holes in the forming process are effectively restrained, a high-quality formed part with the density higher than 99.9% can be stably obtained, the mechanical property of the high-quality formed part is superior to that of a traditional casting part, and a stable and reliable technical basis is provided for industrial additive manufacturing of the alloy.
