Artificial intelligence (AI) for understanding and characterizing the ductile-brittle behaviors of Mg based materials  

On June11^th, the research team led by Prof. Kotiba Hamad at the school of advanced materials science and engineering 

(AMSE)published a paper titled

“Brittle and ductile characteristics of intermetallic compounds in magnesium alloys

: A large-scale screening guided by machine learning” in the Journal of Magnesium and Alloys (IF =11.8) which is ranked the 1^st in the category of metallurgy & metallurgical engineering according to Clarivate’s Journal Citation Reports’ (JCR) ranking. This study is one of the woks conducted by this group to investigate the applicability and the potential of AI techniques in the field of materials discovery and design. The findings of this work showed that, by machine learning (ML), a technique of AI, the brittle-ductile characteristics of intermetallic compounds that form in magnesium-based alloys are reliably, accurately, and quickly predicted. The ML results were validated by theoretical calculations done by density functional theory (DFT), shown by the figure below.  The results can facilitate the designing of magnesium alloys with high performance for structural applications.    

This led to say that, due to the exploding computational capabilities, artificial intelligence, in its machine learning subcategory, has been utilized heavily in the field of material discovery and design for its ability to construct data-driven models that are magnitude faster than conventional experimentation or even physics-driven modeling and simulation. The present research group; Kotiba Hamad (Professor), Russlan Jaafreh (PhD candidate), Kang Woo Seong (Graduate collaborator/Currently working in ‘Computer Systems and Intelligence Laboratory’), and Santiago Pereznieto (Masters Student), have been utilizing the capabilities of AI in the field of material science & engineering, and have published multiple papers regarding this topic in high-tier journals such as: ACS Applied Materials & Interfaces, Journal of Materiomics and many more.
