  • Enhancement of titanium-aluminum alloying by ultrasonic treatment
    Patent number: 4847047
    Abstract: A method of increasing the dissolution rate of titanium or titanium alloys in molten aluminum is disclosed which comprises placing a titanium rod into molten aluminum and applying ultrasonic energy to the rod. The ultrasonic energy enhances the dissolution of the titanium in aluminum, homogenizes the molten alloy, and breaks up particles such as TiAl.sub.3 which form into a layer at the surface of the melt. The application of ultrasonic energy increases the dissolution rate of solid titanium in molten aluminum, decreases the amount of time needed to achieve homogeneity, and results in a titanium-aluminum alloy with a reduction in grain size and improved properties.
