... may be reduced. This observation was first noted by Levy in 1978 ( Ref 28 ), who described steps undertaken at Reynolds Metals to increase ductility in low-pressure die-cast aluminum wheels. Prior to this time, most aluminum wheels in the United States were sold to the automotive aftermarket. The...
