Problems solved by technology

However, the traditional method of connecting amorphous alloys with the help of supercooled liquid regions still has shortcomings: due to the presence of oil, air, etc. There will be defects such as cracks or voids at the connection interface of the bulk amorphous alloy. These defects will become the location where the internal stress is concentrated and released, which will greatly weaken the strength of the prepared bulk amorphous alloy. The above problems increase with the increase of the connection size. big getting worse

Description

technical field [0001] The invention relates to the technical field of amorphous alloy connection, in particular to a method for manufacturing a bulk amorphous alloy and the bulk amorphous alloy. Background technique [0002] Amorphous alloy has the structural characteristics of short-range order and long-range disorder. The special structural characteristics make it have the characteristics of metal and amorphous, solid and liquid. It is a class of engineering materials with great application prospects. It can be used in aerospace, aerospace, 3C consumer electronics, medical equipment and other fields. However, the forming ability of amorphous alloys is limited, and it is difficult to realize the one-time forming of large-sized amorphous alloys by using the traditional vacuum die-casting method, which seriously restricts its application in various fields. [0003] At present, the welding method is often used for the preparation of large-sized amorphous alloys. Patent CN20...
