چکیده انگلیسی
The maximum undercooling ÎTm and thermophysical parameters of Ni-Al alloys were calculated using molecular dynamics (MD) simulations with embedded-atom method (EAM). In the simulations, the solid-liquid interfacial energy γSL was determined using the critical nucleus method (CNM), and a new formula was suggested to predict it. It was found that ÎTm correlates with thermophysical parameters. Based on the correlations, a dimensionless parameter Ï, which only depends on the properties of materials, was developed to predict ÎTm. By replacing the γSL in the expression of Ï with the empirical expression found in this work, a new predicting formula of ÎTm without γSL was further proposed. The consistence between the prediction and experimental data indicates that the predicting formula for ÎTm has good reasonability and universality.
