    摘要:

    为确定烧结温度、材料配比及粒径对铝-特氟龙(Al-Teflon)准静压反应现象的影响, 利用万能实验机对Al-Teflon进行了准静态压缩试验。得到了烧结温度、配比及粒径影响下试件的应力应变曲线及反应率数据。利用扫描电子显微镜(SEM)进行了微观形貌分析。结果表明, 烧结温度、材料配比及粒径均影响材料的力学特性, 改变了材料的形变及裂纹形成模式, 进而影响准静压起始反应的激发; 同时, 材料配比影响反应完全度, 当材料配比偏离化学平衡配比时, 出现不完全反应现象; 而随粒径减小, 反应烈度及反应速率增加。Al-Teflon能够发生准静压反应的材料-工艺范围为:烧结温度320~370 ℃, Al质量分数16%~36%, Al粉粒径小于12~14 μm。

    Abstract:

    To determine the effect of sintering temperature, ratio and particle size on the reaction phenomenon of Al-Teflon under quasi-static compression, the quasi-static compression test of Al-Teflon was conducted using an universal testing machine and the stress-strain curves and reaction ratio data of test specimen under the influence of sintering temperature, ratio and particle size were obtained. The micro morphology of Al-Teflon was analyzed by a scanning electron microscope(SEM). Results show that the sintering temperature, equivalence ratio and particle size can affect the mechanical behavior of Al-Teflon, change the deformation of material and crack formation mode and affect the excitation of the initial reaction under quasi-static compression. At the same time, the ratio affects the completeness of reaction, an incomplete reaction phenomenon happens when the ratio deviates from the chemical equilibrium ratio, and the reaction intensity and reaction ratio increase with decreasing the Al particle size. The material-process range of Al-Teflon reaction occurring under the quasi static compression is that the sintering temperature is between 320 ℃ and 370 ℃, Al mass fraction is between 16% and 36%, and the particle size of Al powder is less than 12-14 μm.
