Abstract
Amorphous alloys exhibit excellent mechanical properties; therefore, application technology development is being attempted in various fields. However, industrial use of application technology is limited owing to the limitations in fabrication. In this study, micropattern fabrication of an amorphous alloy was conducted using laser beam machining. Although microhole fabrication is possible without the deformation of the amorphous phase through nanosecond pulsed laser beam machining, there are limitations in the generation of recast layers and spatters. In cover plate laser beam machining (c-LBM), a cover plate is used to reduce the thermal deformation and processing area. Therefore, it is possible to fabricate holes at the level of several micrometers. In this study, it was confirmed that recast layers are hardly generated in c-LBM. Furthermore, square-shaped micropatterns were successfully fabricated using c-LBM.
