Abstract
In a process of producing monotectic alloys having a relatively large miscibility gap in a liquid state and having in a solidified state a minority phase, which is included in the matrix and has the shape of droplets and has a higher density than the matrix, a molten material which is heated above the segregation temperature is continuously cast at a high casting speed end cooling rats. In order to achieve a sufficiently good disoersion of the minority phase the molten material is cast in a vertical direction.
