A CuAlMn-based alloy having superelastic characteristics and having a recrystallized texture substantially formed of a single phase, in which 70% or more of crystal grains is within a range of 0 to 50 in a deviation angle from <001> orientation of a crystalline orientation measured in a working direction by electron back-scatter diffraction patterning.


The longitudinal direction (rolling direction) and the width direction of a cold processed plate material are indicated. The layout direction of an ingrown nail correction tool material is arranged such that the longitudinal direction of a material of a correction tool body substantially corresponds to the width direction, and the direction in which a material of a nail holder portion is formed substantially corresponds to a direction in which the cold processed plate material is processed. The material of the ingrown nail correction tool is cut out from the cold processed plate material and processed such that the longitudinal direction of the correction tool body of an ingrown nail correction tool is substantially perpendicular to the direction in which the cold processed plate material is processed. The direction in which the nail holder portion is formed substantially corresponds to the direction in which the cold processed plate material is processed.

The fracture and corrosion behaviors of Ni-Ti superelastic alloy have been investigated by carrying out sustained tensile-loading tests in neutral 2% NaF aqueous solutions containing various H 2O 2 concentrations. The times to fracture in solutions with 0.001 M, 0.01 M and 1 M H 2O 2 are shorter than that in a solution without H 2O 2. In the solution with 0.1 M H 2O 2, however, the time to fracture becomes long and the fractographic features are markedly changed. On the basis of the polarization behavior, corrosion is enhanced with increasing H 2O 2 concentration. Under an applied stress above the critical stress for the stress-induced martensite transformation, the fluctuations of corrosion potential and corrosion current density become larger than those without the applied stress. The present results suggest that the fracture and corrosion behaviors of the alloy in neutral fluoride solutions are sensitively affected by the H 2O 2 concentration, but the relationship between fracture and corrosion does not always straightforwardly correspond to the H 2O 2 concentration. © 2012 Elsevier B.V.
