Title: The Innovative Contributions of Hanbing Xu

Introduction

Hanbing Xu is a notable inventor based in Knoxville, TN (US), recognized for his significant contributions to the field of material processing. With a total of four patents to his name, Xu has developed innovative methods that enhance the quality and efficiency of molten metal processing.

Latest Patents

One of Xu's latest patents is focused on the "Degassing of molten alloys with the assistance of ultrasonic vibration." This invention discloses an apparatus and method that utilizes ultrasonic vibration to assist in the degassing of molten metals or metal alloys. By applying high-intensity ultrasonic vibrations to a radiator, cavitation bubbles are created, which induce acoustic streaming in the melt. This process effectively breaks up purge gas, such as argon or nitrogen, that is intentionally introduced into the melt. The result is a reduction in gas content, leading to a cleaner and faster degassing process. In one version of this invention, the molten metal is an aluminum alloy.

Another significant patent by Xu is the "Method and apparatus for semi-solid material processing." This method involves vibrating a molten material at an ultrasonic frequency while cooling it to a semi-solid state. This process forms non-dendritic grains and allows for the shaping of the semi-solid material before it is cooled to a solid state. The method is particularly advantageous as it produces grain sizes smaller than 50 micrometers and can be easily retrofitted into existing conventional forming machines.
