Abstract Scope |
Limited quantitative understanding of complex processing-structure-property relationships of ceramics impedes the new composition and production route development. Utilizing machine learning algorithms in materials science bypasses the need to synthesize and characterize every candidate material, allowing for efficient quantification of the mentioned relationships using prior studies. This study leverages interpretable machine learning models for predicting key mechanical properties, namely fracture toughness, hardness, and flexural strength, of B4C ceramics from processing and structural parameters. A dataset exceeding 250 data points per property, was curated from scientific literature. Different machine learning algorithms were explored to develop the most effective predictive model. The model with the highest predictive power was Gradient Boosting Regression with 11.56%, 11.38%, and 20.77% mean absolute percentage error for fracture toughness, hardness and flexural strength, respectively. Decision mechanisms of the models were analyzed for quantified understanding of processing-structure-property relationships of B4C ceramics. |
