Critical Cooling Rate Prediction by the Reduced Glass Temperature and Fragility Index

Abstract: The reduced glass transition temperature (T rg ) and fragility index (m) are both used to predict the critical cooling rate (R c ). When either T rg or m is individually used to predict log 10 (R c ), a large deviation occurrs in the prediction of log 10 (R c ) because both of the corresponding correlations have low coefficients of determination (R 2 ). The R 2 value increases from either 0.33 (by using only T rg ) or 0.68 (by using only m) to 0.91 by using both T rg and m. Therefore, the glass-forming ability… Show more

“…Therefore, we take into account the alloying compositions and GFA as the input and output, respectively. The GFA was also evaluated by the reduced glass transition (T rg , T g /T l ), which is a credible parameter in the field of MG alloys [35]. To elevate our MBNN model, it is very important to represent attributes associated to the fundamental characteristics of constitutes and the thermodynamic and kinetic features of promising alloys.…”

“…The main physical and mechanical characteristics of amorphous solids are determined by their glass-forming ability (GFA) that is ability to retain the disordered phase without crystallization during rapid cooling of melt [see Fig. 1(a)] [6,7,8,9,10]. For example, silicon dioxide (SiO 2 ) and germanium dioxide (GeO 2 ) with excellent GFA form a stable homogeneous amorphous structure under normal conditions [11].…”
