Diffusion processes in NiTi/Si, NiTi/SiO2 and NiTi/Si3N4 systems under annealing

Thin Solid Films, 2004
Abstract We present a nanometric scale analysis of the NiTi/Si, NiTi/SiO 2 and NiTi/Si 3 N 4 systems before and after annealing at 500 °C during 30 min, by secondary ion mass spectrometry and electron-induced X-ray emission spectroscopy. Before annealing, a few nanometers thick transition layer forms at the interface of each system. Under annealing,

Martensitic Transformation of NiTi and NiTi-TiC Composites

Journal de Physique IV, 1995
Calorimetry and internal friction were used to study the martensitic phase transformation of shape-memory metal matrix composites consisting of nearly equiatomic NiTi with up to 20 vol.% TiC particles. The start and final temperatures for the austenite-martensite transformation (M s , Mf) and martensite-austenite transformation (A s , A f ) arc lower ...

Depositions of Nitrogen on NiTi Instruments

Journal of Endodontics, 2002
This study was designed to obtain nitrogen-rich layers on the surfaces of endodontic files made of nickel-titanium (NiTi) alloy by chemical vapor deposition. Experimental samples (GT rotary instruments) were deposited by using two different methods.
