| Abstract: | Rapidly solidified Al-2.5Ti-2.5Fe and Al-2.5Ti-2.5Fe-2.5Cr alloys were prepared by a melt spinning method. As-quenched and as-annealed microstructures were studied by transmission electron microscopy (TEM), X-ray diffractometry(XRD), EDS and HREM. The influence of the Cr element doping on the as-quenched and as-annealed microstructure and microhardness of rapidly solidified Al-Ti-Fe alloy was also studied. |
