An experimental investigation into the fracture properties of 160-lm-thick edge-cracked specimens of austenitic nickel–titanium (nitinol) under uniaxial tension is presented. Using the in situ optical technique of digital image correlation (DIC), strain fields directly relating to phase boundary nucleation and propagation of fracture samples were observed for the first time. The shape and size ...

Using the in situ optical technique known as digital image correlation (DIC), full-field quantitative strain maps of localization have been experimentally obtained for the first time in thin sheets of Nitinol. The use of DIC provides new information connecting previous observations on the microand macro-scales. It shows that the transformation initiates before the formation of localized bands, ...

Authors’ Response: We greatly appreciate the viewpoints of Dr Jaiman concerning the timing/use of the 4.5-mm reamer when utilizing a flexible reamer for establishing a femoral tunnel. Using a flexible reamer system is very advantageous in creating a low femoral tunnel especially in the current context of concomitant anterolateral ligament (ALL) reconstruction or posterolateral corner reconstruc...

The nitinol-60 shape memory alloy has been rated as the most widely utilized material in real-life industrial applications, including biomedical appliances, coupling and sealing elements, activators, among others. However, less is known about its optimization characteristics while taking advantage to choose best parameter a surface integrity analysis using wire EDM process. In this research, au...

BACKGROUND Aneurysms of the visceral arteries are rare but potentially lethal lesions. We describe a case of a successful endovascular exclusion of a hepatic artery aneurysm in a patient that suffered from chronic abdominal pain. CASE REPORT A 68-year old man presented with chronic abdominal pain that had existed for 10 months. A diagnostic contrast-enhanced CT scan showed an 18 mm atheroscle...

The paper provides a brief review of literature data on the synthesis, processing, structure, mechanical properties, and application nitinol alloys based it, which are promising functional materials found in number high technologies. In addition, machine learning methods were applied to predict temperatures phase transformations.

This article presents a study of fatigue-crack propagation behavior in Nitinol, a 50Ni-50Ti (at. pct) superelastic/shape-memory alloy, with particular emphasis on the effect of the stress-induced martensitic transformation on crack-growth resistance. Specifically, fatigue-crack growth was characterized in stable austenite (at 120 8C), superelastic austenite (at 37 8C), and martensite (at 265 8C...
