چکیده
Although nickel–titanium (NiTi) rotary files are invaluable tools in dentistry, the relationship between their properties and performance has not been elucidated. Herein, of gold heat-treated (ProTaper Gold ProfaTaper Gold), controlled memory (CM)-wire (HyFlex CM V Taper 2H), T-wire (2Shape), R-phase (K3XF) NiTi was evaluated; non-heat-treated ProFile used as control. The bending, buckling, cyclic fatigue, torsional resistances were determined, phase transformation behavior studied through differential scanning calorimetry (DSC). angle rotation until fracture (ARF), ultimate strength (UTS), stiffness evaluated via resistance testing. One-way analysis variance (ANOVA) post hoc analyses conducted using Games–Howell test Tukey’s test. displayed highest buckling (8 N), CM-wire exhibited lowest bending (0.660–0.758 N cm), HyFlex fatigue resistance. ProTaper high UTS low ARF. K3XF demonstrated most suitable for use curved canals, while gold-wire ideal constricted canals. recommended re-treatment cases.

Response of NiTi SMA wire electrically heated
In the present work an experimental-numerical approach is used to study the thermo-mechanical behaviour of NiTi wire for defining what parameters are the most important in actuator designing. Tests were carried out heating, by an electrical current, a wire having a diameter of 150 m, under constant stresses of 200 MPa. Data concerning strain, applied current and voltage are acquired during the ...
متن کاملEffect of Wire Pitch on Capacity of Single Staggered Wire and Tube Heat Exchanger Using Computational Fluid Dynamic Simulation
Single staggered is a design development of normal wire and tube heat exchanger that wires are welded with staggered configuration on two sides. Capacity of wire and tube heat exchanger is the ability of the heat exchanger to release heat. The objective of this study is to analyse the effect of wire pitch (pw) on capacity of single staggered wire and tube heat exchanger. The research...

متن کاملJapanese NiTi alloy wire: use of the direct electric resistance heat treatment method.
Japanese nickel titanium (NiTi) alloy wire possesses excellent spring-back properties, shape memory and super-elasticity. In order to adapt this wire to clinical use, it is necessary to bend as well as to control its super-elastic force, and so a direct electric resistance heat treatment (DERHT) method was developed. An electric current is passed directly through the wire, thus generating enoug...
