数值模拟技术在高温合金中的应用
Numerical Simulation Technology Applications in Superalloys
摘要
Abstract
In cutting-edge technological fields such as aerospace and energy applications,superalloys hold a critical position due to their exceptional performance under extreme thermal-mechanical conditions.Nevertheless,the complex chemical compositions and multi-scale hierarchical microstructures of superalloys present formidable challenges to conventional experimental research.These studies are not only time-consuming,labor-intensive and costly,but also suffer from difficulties in comprehensively controlling numerous interacting factors,resulting in inefficient progress that cannot meet modern industry's urgent demands for superalloy development and performance optimization.With continuous advancements in computational technologies and algorithms,superalloy simulation techniques have emerged as a crucial method in materials science research.By establishing multi-physics field coupling models with high-fidelity,this approach enables profound exploration of the microstructural evolution mechanisms,the macro mechanical response characteristics,and the quantitative correlation between complex process parameters in superalloys,providing scientific basis for material composition design,process parameter optimization,and service performance prediction.This paper outlines representative applications of numerical simulation technologies in superalloy research and discusses future development trends in this field.关键词
