Abstract
The surface nano-deformation behavior in metal matrix composite during tensile loading
was investigated by in-situ atomic force microscope (AFM) observation. The composite material
used was aluminum matrix reinforced with 10 and 20 percent volume fraction of SiC particles. The
average size of the reinforcement was 3 μm. Tensile test and in-situ observations were conducted
using a loading device equipped with an AFM. Surface morphologies of the composite specimens
were acquired before the loading and at various stages of the loading. The microstructural damage
and the evolution of surface roughness were studied. The effect of volume fraction of the reinforcement
on the nano-deformation behavior and damage evolution process of the composite based
on nanoscale in-situ AFM observation will be discussed.
