50Mn18Cr4WN retaining ring macroresidual stress relieving by pulsating oil pressure

A method of macroresidual stress relieving by pulsating hydraulic testing of a 600-MW turbogenerator retaining ring is described. The method is valid for macroresidual stress relieving and does not damage the mechanical properties of the turbogenerator retaining ring. In the test, the macroresidual...

Description
Summary:A method of macroresidual stress relieving by pulsating hydraulic testing of a 600-MW turbogenerator retaining ring is described. The method is valid for macroresidual stress relieving and does not damage the mechanical properties of the turbogenerator retaining ring. In the test, the macroresidual stress decreased by 240 MPa and the dimensions of the retaining ring diameter changed notably.
