| Research Abstract |
In this study, we obtained the following research results that contribute to the development of glass lens forming.(1) As a Pt-free new amorphous alloy suitable for materials of glass forming dieNi_35Nb_40Zr_25 (at.%) and Ni51Nb33Ti16 were found successfully.(2) The measurement method of crystallization temperature (Tx) by emissivity change of samples using thermography was contrived, and then it was succeeded that high-throughput evaluation of Tx and time temperature transformation using the method.(3) Clone die was formed by nano forming of Ni_35Nb_40Zr_25 using a master die made ofNi51Nb33Ti16 having excellent machinability.
