摘要
The mathematical models were developed to predict the ultimate tensile strength (UTS) and hardness of Al/TiB2 MMCs fabricated by in situ reaction process. The process parameters include temperature, reaction time and mass fraction of TiB2. The in-situ casting was carried out based on three-factor five-level central composite rotatable design using response surface methodology (RSM). The validation of the model was carried out using ANOVA. The mathematical models developed for the mechanical properties were predicted at 95% confidence limit.
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。
