Multiple Linear Regression Model for Predicting Yield Strength of HEA by Empirical Parameters
A method to predict the room temperature yield strength of HEA was proposed based on empirical param-eters.Taking empirical parameters as input variables,a multivariate linear regression model was constructed,which performed well in terms of goodness-of-fit(R2)at 0.996.Meanwhile,the average error of predicted yield strength is only 4.2%.Moreover,the empirical parameters exhibiting the most significant influence on yield strength were identi-fied through Pearson's correlation coefficient test,including valence electron concentration,theoretical melting point,mixing enthalpy and entropy-enthalpy ratio.
