Method for manufacturing at least one piece of metallic glass

Abstract

The invention relates to a method for manufacturing at least one molded part (2) in a metallic glass, comprising a step of providing (E1) an injection mold (1) delimiting a cavity (10) which has a textured surface (s10), said textured surface (s10) comprising at least one pattern of miniature structures (11), where each miniature structure (11) has a summit portion (13); an injection step (E3), in which a metallic alloy (3) in the liquid state is injected inside the cavity (10); and a solidification step (E4), in which the metallic alloy (3) is molded to obtain a molded part (2) shaped according to the textured surface (s10), said molded part (2) having at least partially an amorphous structure, and having in the solid state, an elastic limit strictly greater than 2200 MPa.The invention also relates to a molded part (2) and a retaining plate (2a, 2b, 2c) comprising such a molded part (2).
