开发了数学模型来预测原位反应生成的Al/TiB2金属基复合材料的最大拉伸强度和硬度。考察的工艺参数包括反应温度、反应时间和TiB2添加量。采用响应面方法,基于3因素5水平的中心复合旋转来设计原位反应实验方案。对所得模型采用ANOVA方法进行了验证。表明所得的模型对制备的材料力学性能的预测可信度在95%以上。
A mathematical model was developed to predict the maximum tensile strength and hardness of Al / TiB2 metal matrix composites produced by in-situ reaction. The process parameters investigated included reaction temperature, reaction time and the amount of TiB2 added. Response surface methodology was used to design an in situ reaction protocol based on a 3-factor-5 central composite rotation. The obtained model was verified by ANOVA method. The results show that the obtained model has more than 95% confidence in the mechanical properties of the prepared materials.
