Fatigue Behaviour Analysis Of Differently Heat Treated Medium Carbon Steel

Biswal, Sweta Rani (2013) Fatigue Behaviour Analysis Of Differently Heat Treated Medium Carbon Steel. MTech by Research thesis.



The utility of medium carbon steel is well known now-a- days. It has got so many applications in different industries. The importance of fatigue failure of materials is a very important topic in the field of mechanical behavior of materials since 90% of failures resulted from mechanical causes is due to fatigue. In the present work fatigue of medium carbon steel (EN9 grade) has been studied. Since the mechanical properties are greatly influenced by heat-treatment techniques, the effect of various heat treatment operations (like annealing, normalizing, tempering) on fatigue life has been investigated.
The emphasis has been given on the value of endurance limit. The change in the value of endurance limit of the material concerned as a result of various heat-treatment operations were studied thoroughly. It has been found that the specimens tempered at low temperature (2000C) exhibits the best results as far as fatigue strength is concerned.
