| Abstract: | The newly developed alloy under quenched state and the annealed state ( for 10minutes, one hour and 10 hours ) is studied by means of atomic force spectroscopy ( AFM ). The surface of the annealed thin strip, its relation with the annealing time as well as the relation between the roughness and the grain size of the surface are estimated with the mechanism of grain growth at the surface of the annealed sample explored. |
