Abstract
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 out by an originally designed machine under bending in one direction on the cantilever at constant set deflection. The fatigue-proof of Ni-Ti alloy was more excellent than those of Co-Cr and Type IV Au alloys.Keywords
