摘要:
高端制造领域对结构材料的综合性能要求不断提升，传统合金已难以满足严苛环境下的强韧性协同与服役稳定性需求。多主元合金凭借灵活的成分设计实现优异的综合性能，成为新一代结构材料的热点研究方向，而双相多主元合金通过构建复相组织突破了单相结构的性能瓶颈，实现了多种强化机制的协同作用。本文以相组成-性能关系为主线，系统综述了FCC+BCC、FCC+HCP、BCC+B2及BCC+HCP四类双相多主元合金的研究进展。重点分析了各类合金的相形成机制、力学性能及服役性能特征，对比了不同双相体系在强塑性匹配、极端环境适应性等方面的优势与不足。不同相构成对合金性能有显著影响，其中FCC+BCC双相合金通过塑性相与强化相协同实现了宽范围的强塑调控，比如FCC+HCP双相合金依托相变诱导塑性（TRIP效应）展现出优异的强塑协同及低温服役潜力，BCC+B2双相合金凭借析出强化机制具备超高强度与良好高温稳定性，BCC+HCP双相合金通过相变诱导塑性改善了BCC基合金的脆性缺陷。未来，双相多主元合金的研究将一方面深化理论，量化各强化机制的贡献并关联组织成分；另一方面，通过成分优化与先进的制备技术结合，推动双相多主元合金的工程化应用。
Abstract:
As the demand for the comprehensive performance of structural materials continues to increase in high-end manufacturing, traditional alloys are becoming increasingly inadequate in achieving strengthductility synergy and longterm service stability under extreme operating conditions. Benefiting from their flexible compositional design, multi-principal element alloys (MPEAs) have demonstrated outstanding overall properties and have emerged as a key research direction for nextgeneration structural materials. In particular,dualphase MPEAs effectively overcome the intrinsic performance limitations of singlephase alloys by constructing multiphase microstructures,thereby enabling the cooperative operation of multiple strengthening mechanisms. Focusing on the relationship between phase constitution and material properties, this review systematically summarizes the research progress of four representative dualphase MPEA systems, namely FCC+BCC, FCC+HCP, BCC+B2, and BCC+HCP. The phase formation characteristics, mechanical properties, and servicerelated performance are comprehensively discussed. Furthermore, the advantages and limitations of different dualphase structures are comparatively evaluated in terms of strengthductility matching and adaptability to extreme service environments. Different phase constituents exert a remarkable effect on the properties of alloys. FCC+BCC dualphase alloys exhibit a wide tunable range of strength and ductility through the synergistic deformation of ductile and strengthening phases. FCC+HCP dualphase alloys demonstrate excellent strengthductility synergy and promising lowtemperature service potential, primarily attributed to transformationinduced plasticity (TRIP). BCC+B2 dualphase alloys are distinguished by their ultrahigh strength and favorable hightemperature stability, resulting from precipitationstrengthening mechanisms. In contrast,BCC+HCP dualphase alloys effectively alleviate the inherent brittleness of BCCbased alloys through TRIP effect. Looking forward, future research on dual-phase MPEAs should focus on deepening the theoretical understanding of phase stability and controllability, quantitatively evaluating the contributions of various strengthening mechanisms and correlating them with phase constitution and microstructural features. In parallel, the integration of compositional optimization with advanced processing technologies will be essential for translating the promising properties of dual-phase MPEAs into practical applications.
