Pulse Processing of Molten Metals

Article Preview

Abstract:

The use of external physical actions (vibration, ultrasound, etc.) on molten metals is a safe way to change the structure and properties of metals and alloys. Such processing contributes to the formation of a fine structure with an increased level of strength properties. The work covers the results of a relatively new method of molten metals processing with electromagnetic pulses. It shows the results of processing pure metals of zinc and aluminum. The increase in strength properties and the decrease in porosity of the casts have been registered. The article also contains the empiric results of steel rods hot zincing. The zinc alloy was exposed to irradiation directly in the hot zincing bath.
