ABSTRACT OF THE DISCLOSURE A probe is provided for testing or treatment of molten metals, alloys etc. with ultrasound. The probe is provided with a cooling means, near to its tip for contacting the melt, so as to be able to provide a steep temperature gradient over the melt contacting end of the tip. The temperature gradient is such that, when the probe is a steel rod of about one inch diameter, the temperature at a point 2 inches from the melt contacting point is at least 700°C lower than the melt temperature. In rods of other materials and other sizes, an equivalent gradient is created, within the limits of the thermal conductivity of the material and the size considerations. This cooling allows for enhanced transmission of ultrasound signals through the metal probe.
