Effect Of Rolling On Ni-Ti-Fe Shape Memory Alloys Prepared Through Novel Powder Metallurgy Route

This study is concentrated on the preparation of Ni-Ti shape memory alloys with the addition of different atomic wt.% of iron in place of atomic wt.% of Nickel through novel powder metallurgy route. Further rolling was done on hot pressed sample in rolling mill. The microstructure and the mechanical properties of the hot pressed and further rolled sample of Ni-Ti and Ni-Ti-Fe were studied. The DSC and XRD analysis was also done on the hot pressed and rolled samples. The samples were prepared by the powders of Nickel, Titanium and Iron mixed in hexagonal trembler and further cold compaction on hydraulic press.
