Sheet measuring 1mm x 75mm x 2m has been produced from alloys Vit106 and 105 via twin roll casting. Twin roll casting is a production process that is used to produce sheet metal directly from a melt. To prevent the oxidation of the sheet the casting process is performed within a chamber containing an inert atmosphere. To successfully cast strip with an amorphous structure the heat flow of the casting process is controlled. If the cooling is such that regions of the sheet exit the rolls at a temperature above the nose of the continuous cooling transformation diagram then a crystalline structure will be produced. If the exit temperature of the sheet is lower than the glass transition temperature of the alloy then the load on the casting mill will increase to a level that the rolls will stall.
