SiCf/SiC复合材料残余应力的形成机制、表征技术及调控规律
Formation mechanisms,characterization techniques,and regulation strategies of residual stress in SiCf/SiC composites
SiCf/SiC复合材料因其低密度、优异的高温力学性能和抗氧化性,在航空航天高温部件应用中具有广阔的前景,但制备和服役过程中产生的残余应力严重制约了其性能发挥。本文对SiCf/SiC复合材料残余应力的研究进展进行了综述。首先,阐述了微观残余应力与晶格畸变应力的形成机制,明确热膨胀系数失配、相变体积效应和工艺诱导效应是其主要成因。其次,介绍了X射线衍射、中子衍射、拉曼光谱、纳米压痕实验表征技术和有限元法、分子动力学数值模拟方法的原理与优劣。然后,分析了残余应力对复合材料力学性能、环境稳定性和功能特性的调控机制,总结了通过温度梯度控制、界面涂层设计和热处理实现残余应力调控的策略。最后,指出超高温氧化环境下应力动态重构、复杂载荷和热循环下残余应力的原位实时监测以及人工智能驱动的残余应力预测与优化设计是当前面临的前沿挑战。
SiCf/SiC composites have broad prospects for application in aerospace high-temperature components due to their low density, excellent high-temperature mechanical properties, and oxidation resistance. However, residual stresses generated during preparation and service severely restrict their performance. This paper systematically reviews the research progress on residual stresses in SiCf/SiC composites. Firstly, the formation mechanisms of micro-residual stresses and lattice distortion stresses are elaborated, and the coefficient of thermal expansion mismatch, phase transformation volume effect, and process-induced effect are identified as the main causes. Secondly, the principles, advantages, and disadvantages of experimental characterization techniques (including X-ray diffraction, neutron diffraction, Raman spectroscopy, and nanoindentation) and numerical simulation methods (such as finite element method and molecular dynamics) are introduced. Then, the regulation mechanisms of residual stresses on the mechanical properties, environmental stability, and functional characteristics of composites are analyzed, and residual stress regulation strategies through temperature gradient control, interface coating design, and heat treatment are summarized. Finally, it points out that the current frontier challenges include stress dynamic reconstruction in ultra-high temperature oxidation environments, in-situ real-time monitoring of residual stresses under complex loads and thermal cycles, and artificial intelligence-driven residual stress prediction and optimization design.
