A '''metallic glass''', also known as an '''amorphous metal''' or '''glassy metal''', is a metallic material that lacks a crystalline structure. Bulk metals typically have a highly-ordered crystalline structure, whereas a metallic glass is amorphous in nature, much like a glass. Various methods are used to fix the metal's structure in an amorphous state, and the result is a material which possesses a number of novel properties with promising future applications. | |||

A metallic glass, also known as an amorphous metal or glassy metal, is a metallic material that lacks a crystalline structure. Bulk metals typically have a highly-ordered crystalline structure, whereas a metallic glass is amorphous in nature, much like a glass. Various methods are used to fix the metal's structure in an amorphous state, and the result is a material which possesses a number of novel properties with promising future applications.
