Innovative materials: the NiTi alloys in orthodontics

Bio-Medical Materials and Engineering, 1996
Since ten years the NiTi alloys have gained an ever increasing place in orthodontic practice: that is due to their peculiar mechanical properties ascribed to a martensitic thermoelastic transformation which can be thermally or, in a proper temperature range, stress-induced.

Cast NiTi Shape‐Memory Alloys

Advanced Engineering Materials, 2004
The purpose of this study is to build a fundamental understanding of the relationship between the structure and properties of cast nickel‐titanium (NiTi). The structure of the cast material will be analyzed at various scales and will be related to the properties of the cast material such as transformation temperatures, stress‐strain behavior, and ...

The dynamic impact behavior of NiTi alloy

Materials Science and Engineering: A, 2005
The contact force during impact of a NiTi alloy was studied in this paper. The contact force and contact time during impact between a spherical impactor and the specimen at different impact velocity and temperature were measured in real time. The maximum contact force and contact time of the NiTi alloy in the martensite state increased and decreased ...

The tribocorrosion behaviour of NiTi alloy

Applied Surface Science, 2014
Abstract In biomedical applications, NiTi alloys are used mainly because of their favourable shape memory and superelastic properties. However, in many applications the tribocorrosion properties of these alloys can be of critical concern. For this reason the electrochemical and tribocorrosion properties of superelastic NiTi sheet and orthodontic ...

Microstructure of As-cast NiTi alloy

Materials Characterization, 1991
Abstract The metallography of as-cast NiTi alloy, of presumably pseudoelastic composition, is described. Characteristic morphologies, obtained in NiTi microstructure, were produced by different solidification conditions. A method is suggested to avoid the formation of primary hard phases during solidification.

Transformation cycling in NiTi alloys

Journal of Physics F: Metal Physics, 1984
NiTi alloys with different transition temperature sets Ms, TR and Af are considered here to be affected by cycling between the martensite and the parent phase. In alloys with a starting temperature Ms higher than 50 degrees C, Ms can shift on cycling below the critical temperature TR at which a transition to the rhombohedral (R) phase appears.

Corrosion behaviour of NiTi alloy

Electrochimica Acta, 2009
Abstract In the present work, the corrosion behaviour of NiTi in Hanks’ solution at 37 °C was assessed by the use of electrochemical methods. Pure titanium and pure nickel were included in the study in order to understand the contribution of each alloying element.
