Abstract

Materials that are hard to manufacture with conventional manufacturing routes can be fabricated by incorporating the advanced automation. This has motivated the authors to propose a new computational methodology which could help in quantitative and qualitative manufacturing of bulk metallic glasses (BMGs). The present model was designed to propose the critical cooling rate (\( R_{\text{C}} \)) based on glass transition temperature (\( T_{\text{g}} \)), onset crystallization temperature (\( T_{\text{X}} \)) and liquidus temperature (\( T_{\text{l}} \)). Available correlation between \( R_{\text{C}} \) and \( \gamma_{\text{m}} \) parameters has been used to validate the modeled values of \( T_{\text{g}} \), \( T_{\text{X}} \) and \( T_{\text{l}} \). It was observed that obtained results have shown a close resemblance to experimental values of \( R_{\text{C}} \). It was found that Pd-based BMGs exhibited better correlation fit than other families of BMGs. Authors believed that this investigation will be useful for processing of bulk metallic glasses in coming days.
