Sheet fabrication of bulk amorphous alloys by twin-roll strip casting

Twin-roll strip casting has been utilized to fabricate the sheet products of bulk amorphous alloys. Simulation of solidification behavior and actual twin-roll strip casting show that the optimum casting conditions are such that the alloy is in supercooled liquid state at roll nip area rather than fu...

Zusammenfassung:	Twin-roll strip casting has been utilized to fabricate the sheet products of bulk amorphous alloys. Simulation of solidification behavior and actual twin-roll strip casting show that the optimum casting conditions are such that the alloy is in supercooled liquid state at roll nip area rather than fully amorphized.
