The largest amount of latent heat the martensitic transformation in nickel titanium shape memory alloy was explored. measured amounts alloys with different compositions between 48.0 at.% Ni and 51.0 were compared. \(-\) 37.8 J/g absorption 34.8 emission obtained as averaged values several samples equiatomic composition. These magnitudes are close to those novel storage ceramics, VO2 (51 J/g) Ti...

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, conditio...

The aim of this study was to analyze the effect taper and apical diameter nickel–titanium (NiTi) endodontic rotary files on dynamic cyclic fatigue resistance. A total 50 unused conventional NiTi wire alloy instruments were used in study. All submitted a custom-made device until fracture occurred. time failure, number cycles pecking movements, length fractured file tip analyzed using analysis va...

The Hugoniot elastic limit and spall strength were measured for a heat-resistant metal-matrix composite Inconel 625–5%NiTi–TiB2 alloy additive manufactured (AM) by direct laser deposition. characteristics of the obtained from analysis complete wave profiles recorded with VISAR Doppler velocimeter during shock-wave loading samples. samples loaded using PP50 pneumatic gun or ad hoc explosive devi...
