amount difference exceeding the elastic limit as a result the difference between the shrinking amount along the l do line and the shrinking amount along l b d l line finally remains in the metal as an elastic strain at this time when the ceramic member is drawn out from the metal ceramic composite body press fitted at t l the elastic strain is released to shrink the inner diameter of the metallic depression up to d l this shrinking amount of u03b4d l do d l is an interference in case of the fitting at t l lt t o on the contrary when the press fitting is performed at a temperature higher than the transformation temperature being outside the range of the invention or t h gt t o the following is caused that is the diameter of the ceramic protrusion is coincident with the inner diameter of the metallic depression at the temperature t h when the cooling is started from the above state the diameter of the ceramic protrusion shrinks along an h do line shown in fig1 while the inner diameter of the metallic depression tends to shrink along an h a line but the shrinking thereof is obstructed by the ceramic so that the inner diameter shrinks along the h do line therefore at a stage that the temperature falls down to ms point the difference between the shrinking amount along h a m line and the shrinking amount along h do line remains in the metal as an elastic strain however martensitic transformation is occurred at the ms point to expand the metal along an m d h line so that a greater part of the elastic strain.
