Abstract

L'invention concerne un procédé d'usinage d'un échantillon (1) en alliage métallique amorphe à l'aide d'un laser femtoseconde, comprenant au moins une étape d'irradiation de l'échantillon (1) avec un faisceau laser (2) le long d'une trajectoire de référence (TRef) pour ablater de la matière de l'échantillon (1), de façon à obtenir un échantillon (1) usiné et maintenu à l'état amorphe, dans lequel : - le faisceau laser (2) est pulsé, et - la durée de chaque impulsion est inférieure à 1000 femtosecondes, préférablement inférieure à 600 femtosecondes, et - la fréquence (f) de pulsation du faisceau laser (2) est supérieure à 20 kHz; et dans lequel : l'alliage métallique amorphe possède : - un diamètre critique (Dc) inférieur à millimètres, et/ou - une différence (ΔTx) entre la température de cristallisation (Tx) et la température de transition vitreuse (Tg) inférieure à 60°C, et/ou - un quotient (ΔTx/(TI-Tg)) de la différence (ΔTx) entre la température de cristallisation (Tx) et la température de transition vitreuse (Tg) et de la différence entre la température de liquidus (TI) et la température de transition vitreuse (Tg) est inférieur à 0,12.
