In numerous amorphous alloys, it is non-that rare earth (RE) base noncrystal alloy glass forming ability with higher can form block
Peritectic alloy (amorphous alloy that cut off diameter is more than or equal to 1 mm), simultaneously because rare earth element has unique atomic structure, because
And rare-earth-base amorphous alloy typically exhibits the features such as good ductility, high hard magnetic and excellent magnetothermal effect, as
The novel function element with peculiar physical properties prepares material, in many industrial circle tools such as meteorological, military and aerospace
Have wide practical use.And light rare earth base block amorphous alloy therein, i.e., with lanthanum (La), cerium (Ce), praseodymium (Pr), neodymium
(Nd), one of promethium (Pm), samarium (Sm), europium (Eu) and gadolinium (Gd) or multiple element are the amorphous alloy of matrix constituent element, are had
High amorphous formation ability, wide supercooling liquid phase region, superplasticity, excellent electric conductivity and good shape memory effect etc. are excellent
Point makes it show highly important basic research and engineering application value as new structure function integration material.However,
Current existing light rare earth base block amorphous alloy is primarily present following three problems: (1) matrix constituent element (La, Ce, Pr, Nd,
One of Pm, Sm, Eu and Gd or multiple element) and other constituent elements (aluminium (Al), cobalt (Co), nickel (Ni), copper (Cu) and gallium (Ga)

GPa).This will seriously restrict the application of light rare earth base block amorphous alloy.For example, using existing light rare earth base noncrystal alloy as material
When preparing aerospace Mechatronic Systems components, the above problem is unfavorable for realizing the lightweight of such material and device, limitation
The accuracy of manufacture of the service temperature and reduction such material and device of such material and device, and then seriously affect material and device
Military service performance and the service life.
