... Abstract A low-pressure turbine rotor blade failed in service, causing extensive engine damage. A section of the blade broke off around 25 mm from the root platform, producing a flat fracture surface that appeared smooth on one end and grainy elsewhere. Based on their examination, investigators...

... blade. The fracture is intergranular. The crack in the blade was opened to expose the fracture surface. The dark region in one of the corners ( Fig. CH30.5 ) shows that there was a preexisting crack that must have been oxidized. The SEM fractograph of this region also shows intergranular cracking ( Fig...

... is typically used with 400 or 600 grit paper to quickly thin close to the internal bonds. Since the entire device surface is in contact with a large area, wear-out of the lapping material is distributed over a large area. A chemical or plasma etch is then used to remove the remaining epoxy and expose...
