متن کاملDental casting of superelastic Ni-Ti alloy.
Rods of Ni-43.5wt% Ti alloy were prepared under various casting conditions. Specimens which were melted in a cordierite crucible and cast in a phosphate-bonded investment mold had less strength and elongation than those melted in a copper crucible and cast in a phosphate-bonded investment mold. All castings exhibited superelasticity at room temperature. The upper limit of recoverable strain was...
متن کاملFatigue properties of Ni-43.5%Ti superelastic alloy castings.
To evaluate a Ni-43.5wt%Ti alloy as a new alloy for cast clasp, the fatigue properties of its castings were examined and compared with those of Co-Cr and Type IV Au alloys castings. The Ni-Ti alloy was cast into a phosphate-bonded investment mold using an argon-arc melting and pressure casting machine. The Ni-Ti alloy castings showed superelasticity in bending tests. Fatigue tests were carried ...
متن کاملNi-Ti orthodontic archwires at different temperatures
Orthodontic mechanotherapy encompasses the use of several archwires during speci c stages of treatment. Metallic orthodontic appliances consist of bands, arch wires, ligature wires, hooks, tubes, brackets, and springs are daily used in orthodontic practices for the correction of malocclusions in patients ( Oh et al. , 2004 ; Verstrynge et al. , 2006 ; Sabane et al. , 2009 ). One of the most im...
متن کامل[Fundamental studies on superelastic Ni-Ti alloy for wire clasp].
In order to apply Ni-Ti superelastic alloy to wire clasp in dentistry, the bending characteristics and the shape memory treatment of the wire were investigated. The wire cooled in iced water was more easily bent than that stored at room temperature . In both conditions, however, most of the wire specimens were broken by bending before the radius of curvature became less than three times the dia...
