Changes in the atomic structure and surface morphology of a recrystallized molybdenum foil under the action of uniaxial tension in ultrahigh vacuum have been studied by low -energy electron diffraction (LEED) and atomic-force microscopy (AFM). It is established that uniaxial tension of the foil surface, which consists of separate blocks of dominating (100) face with 1 x 1 structure, leads to a local destruction of this face and the rotation of blocks. AFM topographs of various regions on the surface of fractured samples have been obtained. The variation of the LEED patterns agrees well with the evolution of the surface relief measured by AFM.
