【Abstract】 The present and prospective situations of development of aluminum alloy wheel hub was introduced. The mechanism of rare earth scandium rendering the aluminum alloy structure finer was analyzed. The addition of trace scandium to the aluminum alloy can significantly improve its performance. Consequently,prospects of application and development of the scandium-containing aluminum alloy wheel hub is broad,with the result that China’s scandium resource superiority will be brought into full play.更多还原
