Abstract

The method envisages that a melt consisting of metals and metal alloys be subjected to a macrosonic field, at least at the beginning of the solidification process. This produces a pressure amplitude in the molten material and, as a result, as large as possible a number of crystallisation nuclei is produced. The intention is, by influencing the grain growth, to obtain a fine-grained structure in the solidified melt. The device for carrying out the method contains an ultrasonic system comprising an ultrasound generator (converter) 6 and an oscillatory transmission part in the form of a horn (1), which is connected to the ultrasound generator (6) via an intermediate piece (5), the length of which is matched to the wavelength of the ultrasound. The horn (1) forms an oscillatory bottom to the casting mould, in which it is mounted to allow displacement in the plane of a node of vibration. <IMAGE>
