Engineering Contradiction Analysis
1Measurement precision
If conventional prediction methods are used for aluminum microstructure, then the manufacturing process is simpler, but the prediction accuracy is insufficient
Solution Approach 1:
The microstructure prediction system is segmented into multiple independent calculation modules, each responsible for a specific metallurgical phenomenon (precipitation, solid solution, grain growth, etc.). This allows the complex prediction task to be divided into manageable components that can be executed sequentially or in parallel, improving accuracy while maintaining computational feasibility.
Solution Approach 2:
The microstructure prediction apparatus is designed as a universal system that can handle multiple metallurgical phenomena through a common framework. The system integrates various calculation modules that can process different types of microstructural changes (precipitation, dissolution, phase transformations) using unified data structures and processing logic, making the complex system applicable to diverse aluminum alloy processing scenarios.
2Measurement precision
If multiple metallurgical phenomena are considered simultaneously, then the prediction accuracy improves, but the calculation complexity increases
Solution Approach 1:
Each metallurgical phenomenon is modeled by a separate calculation module that independently processes its specific kinetics and thermodynamics. This segmentation allows complex multi-phenomenon interactions to be handled through modular computation, where each module contributes its specific effects to the overall microstructure evolution without requiring a single monolithic complex model.
Solution Approach 2:
The system merges multiple calculation modules that each handle specific metallurgical phenomena into a unified microstructure prediction framework. The modules are combined through a common data structure that tracks microstructural parameters across all phenomena, allowing simultaneous consideration of precipitation, solid solution, grain growth, and other effects through integrated computation.
3Measurement precision
If detailed thermo-mechanical processing conditions are simulated, then the microstructure prediction accuracy improves, but the computational time increases
Solution Approach 1:
The system performs preliminary calculations by pre-defining calculation modules for each metallurgical phenomenon and preparing the computational framework before actual microstructure prediction. This preliminary setup includes establishing data structures, defining kinetic parameters, and configuring the integration algorithm, which reduces computational overhead during the actual prediction process while maintaining high accuracy.
Solution Approach 2:
The calculation modules continuously track microstructure evolution throughout the entire thermo-mechanical processing sequence without interruption. The system maintains continuous computation of microstructural parameters from initial state through all processing steps to final state, ensuring that no critical transitions are missed and enabling accurate prediction of cumulative microstructural changes efficiency.

AI summary
An object is to predict a microstructure of Al in an industrial process more accurately than conventional techniques. In an information processor (1), an inter-step information integration section supplies a PC(i) and an MS(i, 0) to each i-th step calculating section included in a step calculating section. Each i-th step calculating section supplies an MS(i, t) and a TMP(i, t) to a microstructure calculating section and thereby causes the microstructure calculating section to find an MS(i, tfi), and supplies the MS(i, tfi) to the inter-step information integration section (11). The inter-step information integration section (11) sets, as an MS(i+1, 0), the MS(i, tfi) received from the i-th step calculating section.
