Microstructures and Properties of Ti-25Nb-15Zr Alloy for Spectacle Frame
Keyword(s):
Mechanical properties and microstructures of a new β Ti-25Nb-15Zr alloy for spectacle frame were studied. The results show that the optimum cold rotary swaging reduction of the alloy is between 50% and 70%. The wire of 3mm in diameter exhibited an equiaxed microstructure consisting only β single phase and fine grain with less than 10mm size when the alloy is heat treated at 1003K for 1.8Ks. While it has good shape memory property, and the maximum complete recovery strain was up to 3% at room temperature. At the same time, the flattened frame legs were solution-treated to improve their elastic behavior, so the residual strain was completely or partly recovered due to transformation of the microstructure.
