Metallic alloys are critical to essentially all advanced technologies and engineered systems. The well-documented impact of corrosion (and oxidation) of alloys, remains a significant industrial and economic challenge, year on year. Recent activity in the field of metallurgy has revealed a class of metallic alloys, termed multi principal element alloys (MPEAs) that present unique physical properties. Such MPEAs have in many instances also demonstrated a high resistance to corrosion – which may permit the broader use of MPEAs as corrosion resistant alloys (CRAs) in harsh environments. Herein, the progress in MPEA research to date, along with prospects and challenges, are concisely reviewed—with potential future lines of research elaborated.

金属合金对于基本上所有的先进技术和工程系统都是至关重要的。有据可查的合金腐蚀（和氧化）影响每年仍是重大的工业和经济挑战。冶金领域的最新活动揭示了一类金属合金，称为多主要元素合金（MPEA），具有独特的物理性能。这种MPEA在许多情况下还表现出很高的耐腐蚀性-这可能允许MPEA在恶劣环境下更广泛地用作耐腐蚀合金（CRA）。在此，简要回顾了MPEA迄今为止的研究进展以及前景和挑战，并详细阐述了潜在的未来研究方向。
