A primary challenge in the development of high-entropy alloys (HEAs), particularly biocompatible variants, is the substantial cost associated with experimental trial-and-error procedures. In this study, machine learning (ML) models were employed to predict phase formation—specifically, solid solution (SS), intermetallic (IM), and composite (SS+IM) phases—to minimize experimental overhead and expedite the alloy design process. A reference database comprising approximately 400 HEAs was utilized, with key thermodynamic parameters—namely ΔHmix, ΔSmix, δ, VEC, and Δχ—serving as input features. Two primary learning frameworks were evaluated: the Random Forest (RF) algorithm and ensemble learning techniques, specifically Bagging and Boosting. The results indicate that the three-phase classification accuracy reached over 75% on average using the Random Forest and Bagging methods. This study demonstrates that these ensemble algorithms constitute effective, cost-efficient computational tools for phase prediction in HEAs, significantly accelerating the design of novel alloys tailored for biomedical applications and orthopedic implants.
