Abstract
A method of imparting superior fatigue performance to a vehicle wheel cast from a magnesium alloy by selective application of friction stir processing to regions of the casting known to be subject to high in-service stresses is described. The method may be particularly applicable to open wheel designs in which a plurality of spokes is used to connect the hub and rim portions of the wheel.
