    MoSi2 single crystals in the soft 201 orientation and polycrystals were deformed in constant strain rate tests in compression between 300 and 1200°C for single crystals and between 495 and 1250°C for polycrystals. Stress relaxation and temperature change tests were performed to determine the activation parameters of the deformation.

    In general the plastic deformation of a single crystal can be divided into two types slip and twinning (Figure 2 a) 29 . Slip refers to sliding of a part of the crystal on a certain crystal plane (slip plane) along a certain direction (slip direction) relative to another part under the action of shear stress.

  • The relation between polycrystal deformation and single

    A phenomenological description of crystallographic slip and pencil glide in single crystals is outlined with emphasis on the behavior under prescribed strains. Theoretical relations are established between these single-crystal properties and the behavior of quasi-homogeneous quasi-isotropic polycrystals deforming uniformly on a macroscopic scale at subdiffusive temperatures.
