Description
Technical field
The invention belongs to apparatus for fixing transformer technical fields, more particularly, to a kind of Silencing clip of amorphous alloy transformer
Part.
Background technology
There are two types of the materials of daily people's contact：One is crystalline material, another kind is amorphous material.So-called crystalline state material
Material, refers to that the atomic arrangement of material internal follows certain rule.Conversely, interior atoms arrangement be in random state, then for
Amorphous material, general metal, interior atoms aligned orderly belong to crystalline material.Scientist has found that metal is melting
Afterwards, interior atoms are in active state.Once metal is begun to cool, atom will with the decline of temperature, and at leisure according to
Certain crystalline state rule is lined up in an orderly manner, forms crystal.If cooling procedure is quickly, atom also has little time to rearrange just
It has been be solidified that, thus just produce amorphous alloy, prepared a kind of exactly technique quickly solidified of amorphous alloy use.
