Abstract: The invention belongs to the field of amorphous alloys, and more specifically, relates to a method for calibrating the internal temperature field of amorphous alloy prepared by spark plasma sintering. First, the part required for temperature field calibration inside the bulk amorphous alloy sample obtained by spark plasma sintering is cut into a series of small amorphous alloy samples, and the isothermal crystallization treatment is performed to obtain the crystallization time of different parts of the sample. An annealing-isothermal crystallization experiment is performed on the adopted amorphous alloy powder at different annealing temperatures, and the functional relationship between the annealing temperature and the crystallization time is obtained.

Abstract: Described are methods for promoting increase in plant biomass and yield. This increase has its visible effects in organs such as leaf, stem, root and production of fruits and seeds. Further described is the increase in tolerance of those plants to drought, generating plants better adapted to the environmental changes, improving their growth, biomass and yield.

Abstract: The invention provides a method and a product for manufacturing a titanium alloy dual-structure turbine disk based on partial hydrogenation, which includes the following steps: coating a glass coating on the partial surface of a titanium alloy billet where hydrogen-blocking is required, and sintering the titanium alloy billet coated with the glass coating; performing hydrogenation treatment on the titanium alloy billet, such that the hydrogen concentration at the hydrogenation-required portion reaches the predetermined level; removing the glass coating from the titanium alloy billet; preheating the titanium alloy billet, and then performing high temperature die forging in the forging dies; performing vacuum dehydrogenation treatment on the forged turbine disk to remove hydrogen element inside the forging, so that the hydrogen content is 0.015 wt. % or less.

Abstract: The invention belongs to the field of additive manufacturing of amorphous alloy, and discloses a laser 3D printing forming system of amorphous alloy foil and a forming method thereof. The unnecessary material of the amorphous alloy foil is cut by a first laser and then the remaining portion is selectively scanned and heated by a second laser so that the amorphous alloy is heated to be in a superplastic state in the supercooled liquid region. Then, the amorphous alloy foil is rolled by a preheated roller in combination with the ultrasonic vibration to achieve interatomic bonding between layers of the amorphous alloy foil, and the amorphous alloy foil is then rapidly cooled, so that an amorphous alloy part with a large size, a complicated shape and a porous structure is formed.
