Using neutron diffraction we determined internal residual stress in the stainless steel AISI 310S carrier tape with a thickness of 100 μm and a width of 4 mm after mechanical polishing and the ABAD deposition of the textured YSZ buffer layer. It is shown that mechanical polishing causes a slight distension of the tape in the rolling plane. After the deposition of the YSZ layer, uniform tensile stress of 70 MPa isotropic in the rolling plane was observed inside the tape. Calculations have shown that it results from relaxation of compressive stress acting on the surface of the tape in a layer several times thicker than the YSZ layer. It is assumed that the surface of the tape is plastically deformed during the YSZ deposition. Keywords: residual stress, YSZ buffer layer, HTS-2G wire, AISI 310S carrier tape, neutron stress diffractometry.

The method of neutron stress diffractometry has been used to study a distribution of residual stresses in the stainless steel AISI 310S ribbon, of 100 μm thick and 4 mm wide, in three directions – along, across and perpendicular to rolling plane. The residual macro stresses averaged over the ribbon length of 40 cm are determined. The longitudinal, transverse and normal macro stresses are respectively –71±21 MPa, –31±16 MPa, and –11±16 MPa on one edge of the ribbon and +30±19 MPa, +64±16 MPa, and +30±16 MPa on the other edge. Such distribution of macro stresses compressing the ribbon on one edge and stretching it on the other edge is inherent for so-called crescent-shaped deformation of the ribbon – its bending in rolling plane along rolling direction. A correlation between the macro stresses magnitude and the micro stresses presence has been observed – the stronger macro stresses the higher concentration of micro stresses.
