Abstract

The relatively low creep resistance of magnesium (Mg) alloys limits their application in high-temperature environments. Mg-Gd-based alloys, however, exhibit exceptional creep resistance, making them promising candidates for such applications. This review comprehensively examines recent advancements in the characterization and optimization of Mg-Gd-based alloys, focusing on key factors influencing their creep resistance. Key strategies for improving creep resistance include precise composition optimization with rare-earth elements such as Y and Nd, combined with Zn, Ca, Mn, and Al elements to alter precipitation behavior and enhance thermal stability. Thermomechanical processing has emerged as a critical tool to further improve creep resistance by tailoring grain structure and precipitation states. Furthermore, the review highlights the integration of machine learning to predict and design creep-resistant alloys, enabling cost-effective and accelerated development pathways. The discussion extends to future perspectives in optimizing Mg-Gd-based alloys for diverse industrial applications. This work serves as a detailed guideline for researchers and engineers aiming to advance the field of high-temperature Mg alloy development.

抗蠕变mg - gd基合金的研究进展

镁合金相对较低的抗蠕变性能限制了其在高温环境中的应用。然而，mg - gd基合金表现出优异的抗蠕变性能，使其成为此类应用的有希望的候选者。本文综述了mg - gd基合金在表征和优化方面的最新进展，重点介绍了影响其抗蠕变性能的关键因素。提高抗蠕变性能的关键策略包括精确优化稀土元素（如Y和Nd）的成分，并与Zn、Ca、Mn和Al元素结合，以改变析出行为并提高热稳定性。热机械加工已成为通过调整晶粒结构和析出状态来进一步提高抗蠕变性能的关键工具。此外，该综述还强调了将机器学习集成到预测和设计抗蠕变合金中，从而实现成本效益和加速开发途径。讨论扩展到优化mg - gd基合金用于各种工业应用的未来前景。这项工作为旨在推进高温镁合金开发领域的研究人员和工程师提供了详细的指导。图形抽象
