| The plant manufactures polycrystal, monocrystal silicon, synthetic quarz cups. |
| Structure of interface between layers of different metals, which enter into composition of the condensate, is similar to the big-angle intergrain boundary in a polycrystal. |
| We next build a framework of polycrystal plasticity based on the idea described above. |
| Conclusions concerning polycrystal deformation are drawn. |
| Monocrystal and polycrystal elastic constants of titanium diboride. |
| Yttrium-stabilized tetragonal zirconia polycrystal. |
