Effect of ball milling on NiTi powder metallurgy alloy

Mechanical alloying, especially nickel-titanium alloys, has attracted great interest recently as researchers strive to enhance the properties of nanocomposites, expand their usefulness, and how produce them at minimal costs homogeneous fine powders.In this paper, high-energy ball milling was used Ti-Ni ultrafine powders. The effects grinding parameters such tools initial state powders, conditions operating times, in addition effect equal size balls speed machine, were investigated, while avoiding contamination powders contact with air by applying silica. Milling process X-ray diffraction, SEM, EDS, plus particle size.
