Nickel-titanium alloys: A systematic review
Results: Nickel-titanium wires show exceptional features in terms of elasticity and shape memory effects. However, clinical applications request a deeper knowledge of these properties in order to allow the professional to use them in a rational manner. In addition, the necessary information regarding each alloy often does not correspond to the information given by the manufacturer. Many alloys ...
متن کاملPseudoelasticity and thermoelasticity of nickel-titanium alloys: a clinically oriented review. Part II: Deactivation forces.
The purpose of this review was to organize a systematic reference to help orthodontists evaluate commonly used orthodontic nickel-titanium alloys. Part I of the article reviewed the data available in the literature regarding the temperature transitional ranges of the alloys. The thermomechanical behavior of these compounds is, in fact, strictly dependent upon the correlation between the tempera...

متن کاملPower-law creep in near-equiatomic nickel–titanium alloys
The compressive creep behavior of nickel-rich B2–NiTi (with 50–140 lm grain size) was studied over the stress range 3–11 MPa and the temperature range 950–1100 C. The stress exponent (n = 2.7) and activation energy (Q = 155 kJ mol ) are compared with a literature review of NiTi creep studies performed over lower temperature and/or higher stresses. Possible explanations for discrepancies between...
متن کاملAn overview of nickel-titanium alloys used in dentistry.
The nickel-titanium alloy Nitinol has been used in the manufacture of endodontic instruments in recent years. Nitinol alloys have greater strength and a lower modulus of elasticity compared with stainless steel alloys. The super-elastic behaviour of Nitinol wires means that on unloading they return to their original shape following deformation. These properties are of interest in endodontology ...
