| Abstract: | Conclusions It was found that during operation of cylinder heads complex physicochemical processes of internal oxidation occur in the thermally stressed section of the lower wall due to the influence of the exhaust gases. The service life of the cylinder head is determined by the changes in the properties resulting from these processes.Structural changes due to graphitizing of eutectoid cementite were not observed due to the submicroscopic character of such changes and the substantial heterogeneity of the metallic cast iron in the cylinder heads examined.Translated from Metallovedenie i Termicheskaya Obrabotka Metallov, No. 6, pp. 66–67, June, 1970. |
