Experimental results which were described in the previous five reports have been ascertained by the tests using actual rotor forgings in works in this 6th report. (1) Type B deflection is attributable to the relaxation of residual stresses, and does not appear again, unless re-machining is applied. (2) Deflection for which it is necessary to perform the heat treatment to be eliminated is type C only. (3) Spray coating with a mixture of flake graphite powder and heat resistance enamel is one of the practical techniques to eliminate the deflection of types A, D and C' in works, Consequently, no heat treatments are necessary to eliminate these three types of deflection. At the heat indication test of turbine and generator rotor forgings, only deflection of types B and C should be examined closely, and the other types of deflection i.e. A, D and C'are generally considered harmless.
