摘要
A method for cutting a primary ultrafine-crystalline alloy ribbon having a structure in which ultrafine crystal grains having an average grain size of 30 nm or less are dispersed in a proportion of 5-30% by volume in an amorphous matrix, comprising placing the ribbon on a soft base deformable to an acute angle by local pressing, bringing a cutter blade into horizontal contact with a surface of the ribbon, and pressing the cutter to the ribbon to apply uniform pressure thereto, thereby bending the ribbon along a cutter blade edge to brittly fracture-cut the ribbon.
