Residual stresses in parts with expanded flanges made from L63 and AK7 alloys

We’re sorry, something doesn't seem to be working properly.

Please try refreshing the page. If that doesn't work, please contact support so we can address the problem.


Parameters of the strained and stressed states of surfaces layers of parts of grade AK7 aluminum alloy and grade L63 copper alloy, which are made by rolling, with flanges very far from the end of the blank are investigated by the X-ray diffraction method. Residual stresses in the surface layers of parts are determined. Graphs of changes in residual stresses in the depth of the deformed areas are constructed.
