Narrative:

The aircraft had a discrepancy, or write-up, of an engine overspd on the previous leg (dsm-atl). Myself (captain) and first officer performed a run-up with a mechanic to see if this airplane was safe to ferry back to cvg. All parameters were normal and the aci was signed off by the mechanic for a 1 time ferry flight. We had normal indications throughout takeoff roll and initial climb until passing 17500 ft the #2 engine went hot and performed an automatic shutdown. My first officer performed all memory items and checklists. I declared an emergency and returned to the airport. We did not have any fire indications. However, I purposely kept the airspeed on the fast side as I was concerned about structural damage. At no time did I violate any airspeed or airspace regulations. Conditions were VMC and I made a landing on runway 8L while crash fire rescue equipment was standing by. After crash fire rescue equipment inspected the engine visually, it was determined to be safe to taxi to the gate. Upon postflt inspection, the engine indicated it had reached temperature as high as 990 degrees C during the automatic shutdown.
