Abstract: Analyses on the stress in the carbon nanotube/Fe3Al composites were performed. The biphase interface valence electron structure was established on the basis of Pauling’s nature of the chemical bond. The stress occurs by the huge interface electron density difference, which will block the Fe3Al grain agglomeration and growth. With the X-ray diffractions, the calculated magnitude of compressive stress existing in the CNT/Fe3Al interface is 0.38 GPa. The experimental result verifies that the stress has a positive effect on the enhancement of mechanical properties of composite.
