Deformation and structure-forming processes have been studied in hot-formed Fe-40at.%Al - based castings. The quality of castings has been optimized by utilizing high-power ultrasound for solidifying of the melt. The subsequent thermomechanical treatment of such an as-cast alloy is usually difficult, mainly because of fraying and cracking of the formed alloy. The main reason for the poor quality of such hot-formed products is the thermal shock arising at the surface of the hot casting, when the casting is coming into contact with the cold roller or press. A special stainless steel bandage of the casting solved the problem successfully.
