Cooling times’ dependence on the glassy NiTi at extremely low temperatures: a result from rapid solidification using molecular dynamics simulations

Abstract

Abstract In this paper, we evaluate the structure of glassy NiTi at 10 K obtained from molecular dynamics simulations using various cooling times. The final configurations of glassy NiTi were produced by decreasing the temperature of liquid NiTi rapidly from 2500 K to10 K during 0.1 nanoseconds (ns) to 1.0 ns of cooling times. The results show that the count of BCC-like and Icosahedral-like local structure increases at the longer cooling times, while the count of HCP-like local structure decreases when the cooling times become longer. We also observe that the count of FCC-like local structure almost remains constant for all cooling time variations.
