Mechanical properties of amorphous alloys ribbons prepared by rapid quenching of the melt after different thermal treatments before quenching

The mechanical properties of amorphous alloy are greatly influenced by the thermal treatment of its melt before rapid quenching. The strength and the fracture toughness of some amorphous alloys obtained after melt heating above the melt critical temperature TCR are essentially higher than those obtained from melts that were not heated above TCR. This difference is considered to be caused by changes in the melt atomic structure under heating above TCR.
