Abstract
The invention provides a method for preparing a high-plasticity amorphous composite material. The method at least includes: providing an amorphous alloy sample and maintaining an inert atmosphere to isolate oxygen; heating the amorphous alloy sample to an annealing temperature, and performing An annealing treatment step to induce nanocrystallization to obtain a crystal / amorphous composite material, wherein the annealing temperature is greater than or equal to the glass transition temperature of the amorphous alloy sample; removing the surface of the crystal / amorphous composite material The oxide layer is obtained to obtain a crystal / amorphous composite material after the oxide layer is removed; the crystal / amorphous composite material after the oxide layer is removed is subjected to a molding treatment step to obtain the high-plasticity amorphous composite material. The plastic and mechanical properties of the amorphous composite material obtained according to the preparation method provided by the invention are ideal.
Description
technical field [0001] The invention relates to the technical field of research on amorphous alloy materials, in particular to a method for preparing high-plasticity amorphous composite materials. Background technique [0002] Amorphous alloys, also known as metallic glasses, are usually formed by rapid solidification of liquid metals (cooling rates generally greater than 10 6 K / s), obtained by suppressing the formation of thermodynamically stable crystals. Amorphous alloys have been developed into a variety of systems. Due to their high glass forming ability, high strength, low modulus, good impact toughness, good biocompatibility and corrosion resistance, they have attracted widespread attention. New functional and structural materials with potential applications. However, the room temperature plasticity of amorphous alloy materials is extremely poor, so that it often produces brittle fracture without warning during service, causing catastrophic consequences, thus greatl...
