Abstract: Embodiments herein relate to a method of making roll formed objects of a bulk solidifying amorphous alloy comprising a metal alloy, and articles thereof. The roll forming includes forming a portion of the bulk solidifying amorphous alloy at a temperature greater than a glass transition temperature (Tg) of the metal alloy. The roll forming is done such that a time-temperature profile of the portion during the roll forming does not traverse through a region bounding a crystalline region of the metal alloy in a time-temperature-transformation (TTT) diagram of the metal alloy.
