This Small Business Innovation Research Phase I project entitled ""USV-Grain Refining"" aims at advancing the grain refining technologies for the production of aluminum or magnesium alloy ingots or castings. Grain refining is usually one of the first processing steps for the production of metal and alloy products. The conventional methods use chemical grain refiners that contain foreign particles. These methods have limited capability in reducing grain size, and foreign particles added into molten metals lead to defect formation during materials processing. This project will combine the latest technologies of processing of lightweight materials using ultrasonic vibration (USV) and continuous casting or direct chill casting technology, and to demonstrate the feasibility of an enabling technology for producing metal ingots of ultrafine grains without the use of foreign particles for grain refining. The new technology will provide cost effective opportunities for producing metal and alloy
