demonstrates clearly
that RDC process offers better mechanical properties than both
thixocasting and NRC processes in terms of increased strength
and ductility. For direct comparison, the mean values of mechanical
properties in Fig. 9 are used to present the mechanical
properties of each process. The improvement of strength by the
RDCprocess is17%over thixocasting and13%over NRC, while
the ductility is higher than that of NRC process.
