Abstract

The high temperature compression test of Be/2024Al composites with 62wt% Be was conducted at 500–575°C and strain rate of 0.003–0.1 s⁻¹. The strain-compensated Arrhenius model and modified Johnson–Cook model were introduced to predict the hot deformation behavior of Be/2024Al composites. The result shows that the activation energy of Be/2024Al composites was 363.364 kJ·mol⁻¹. Compared with composites reinforced with traditional ceramics, Be/2024Al composites can be deformed with ultra-high content of reinforcement, attributing to the deformable property of Be particles. The average relative error of the two models shows that modified Johnson–Cook model was more suitable for low temperature condition while strain-compensated Arrhenius model was more suitable for high temperature condition. The processing map was generated and a hot extrusion experiment was conducted according to the map. A comparation of the microstructure of Be/2024Al composites before and after extrusion shows that the Be particle deformed coordinately with the matrix and elongated at the extrusion direction.

Be/2024Al复合材料的热变形行为及显微组织演变

对Be含量为62wt%的Be/2024Al复合材料在500 ~ 575℃、应变速率为0.003 ~ 0.1 s−1的条件下进行高温压缩试验。采用应变补偿Arrhenius模型和修正Johnson-Cook模型预测了Be/2024Al复合材料的热变形行为。结果表明，Be/2024Al复合材料的活化能为363.364 kJ·mol−1。与传统陶瓷增强复合材料相比，由于Be颗粒的可变形性，Be/2024Al复合材料可以在超高增强量下变形。两种模型的平均相对误差表明，修正Johnson-Cook模型更适用于低温工况，应变补偿Arrhenius模型更适用于高温工况。生成了加工图，并根据图进行了热挤压实验。挤压前后Be/2024Al复合材料的显微组织比较表明，Be颗粒与基体协调变形，并在挤压方向上拉长。
