Production of nanostructured Ni-Ti-Ag alloy by mechanical alloying [electronic resource]
, Article Advanced Materials Research ; Volume 829, 2014, 67-72 ; Sadrnezhaad, Khatiboleslam ; Bagheri, Gh. Ali ; Sharif University of Technology
Abstract
Because of corrosion resistance and antibacterial effects, shape memory Ni-Ti-Ag alloy can be considered for different biomedical applications. Mechanical alloying is used to produce nanostructured Ni-Ti-Ag alloy from elemental powders. X-ray diffraction (XRD) and field emission scanning electron microscopy (FESEM) are used to characterize the product. Results show that after 1h milling, homogenous distribution of the elements occurs; while no intermetallic compounds is observed. After 3h milling, titanium dissolves in nickel to form amorphous and nanostructured solid phases. Peaks of B2 phase appear in the XRD pattern after the 3h milling of the powder mixture. Sintering of the 3h-milled...
