Amorphous/amorphous nano structured alloy

Abstract

The present invention belongs to the field of amorphous nanometer alloy, and is suitable for making amorphous / amorphous nanometer alloy. Chemically, the alloy of the present invention consists of Mo 2-14 wt%, Cr 3-14 wt%, Ni 1-6 wt%, P 4-8 wt%, Si 1-5 wt%, B 1-4 wt%, C less than 0.5 wt% and impurity less than 1 wt%, except Fe. The alloy has low critical cooling speed, so that amorphous alloy powder may be obtained through common fast cooling method. By means of proper temperature lowering speed control, amorphous structure and nanometer crystal may be obtained. The amorphous nanometer structure alloy has relatively high crystallization temperature of 770-820 deg.c, and the advantages of both amorphous and nanometer crystal, and may be used to produce alloy powder and product with high hardness, high corrosion resistance, high wear resistance, etc. In addition, the alloy material has relaxed impurity requirement, low cost and simple preparation process.

Description

Technical field: [0001] The invention belongs to the field of amorphous / amorphous nano-alloys, and is mainly used in manufacturing or forming amorphous / amorphous nano-structure alloy materials and powders. Background technique: [0002] At present, the application of amorphous materials is mainly in the fields of electricity and magnetism, and its good mechanical properties have not been well utilized. The main reason is that the formation of amorphous alloys requires relatively high cooling rates. Therefore, it is difficult to form bulk amorphous material. Therefore, most of the current amorphous surfaces are obtained by methods such as surface treatment or spraying. [0003] The current research on nanomaterials has penetrated into many fields. Nanomaterials have special electrical, magnetic and mechanical properties due to their unique physical properties. Most of the current applications are to generate microscopic materials such as nano-powders and nano-whiskers, but...
