Cu
Oy-coated conductors creates different morphologies of columnar defects (CDs) depending on the irradiation angles relative to the c-axis: continuous CDs with a larger diameter are formed for oblique irradiation at 
= 45
, whereas the same ion beam at a different angle ( = 0) induces the formation of discontinuous CDs. The direction-dependent morphologies of CDs significantly affect the angular behavior of the critical current density

Cold cracking test was conducted using Y-grooved constraint weld joint by intentionally introducing hydrogen gas, and critical hydrogen content in the weld metal to cold cracking was determined. Residual stress distribution in the weld meal was measured by neutron diffraction technique. The root portion showed highest tensile stress of over 1110 MPa in the transverse direction, which is the same as the crack opening direction.

Experiments of cold cracking on a hydrogen induced 980 MPa class restraint weld joint were performed and the residual stress distribution in the joint was analyzed using neutron diffraction technique. The critical conditions for the cold cracking of the weld joint was determined from the obtained results.
