AI-based Materials Design and Development of Advanced Metals and Alloys


   School of Advanced Technology

  , Prof Yuwen Cui, ,  Applications accepted all year round  Funded PhD Project (Students Worldwide)

About the Project

1) Multi-source database creation and feature processing

Evaluate R&D, testing, production and literature data, establish a multi-source database covering alloy composition, processing conditions, and microstructural characteristics, and with the yield strength as the target property. Referring to the strategy of the computational thermodynamics and kinetics, sort and feature the selected data in order to construct high-fidelity core dataset on yield strength property.

2) Development of the multi-fidelity data fusion algorithm

The residual-connection multi-fidelity data fusion is utilized to perform multi-fidelity data fusion on the processed data. In this project, the computational simulation and micro-nano test datasets are selected as low-fidelity data while the yield strength test dataset is high-fidelity data.

3) Development of deep learning model and code

Based on the open source Scikit-learn library, a supervised Python deep learning code is developed based on the artificial neural network to predict the yield strength of the target alloy system. Through the training of the fused dataset, the optimal neural network model is found, the appropriate hyperparameters are determined, and the cross-validation is carried out to complete the machine learning prediction of yield strength.

4) Continuum constitutive model based on material data

Under the framework of continuum mechanics, we’ll establish a constitutive model based on material data, analyze the differences from classical models and perform finite element analysis.

5) AI design prototype

By putting all tasks together and iterating, it is to framework an AI design prototype for the yield strength performance of target alloys.

Funding Notes

This PhD project is a collaborative research project between XJTLU
(View Website) in Suzhou and JITRI (Jiangsu Industrial Technology Research Institute) Advanced Materials Research Institute, Yangtze Delta (Suzhou). The student will be registered as an XJLTU PhD student but is expected to carry out the major part of his or her research at the Institute in Advanced Materials Research Institute, Yangtze Delta. The PhD studentship is available for three years subject to satisfactory progress by the student. The award covers tuition fees for three years (currently equivalent to RMB 80,000 per annum).
