Spheroidising changes cementite from a lamella formation to
a formation based on an alpha ferrite matrix with particles
of spheroidal cementite (Fe3C)embedded. This resulting
steel has improved ductility and toughness compared to the
original steel with reduced hardness and strength.
This is done for ball bearings to avoid non-elastic
deformation of balls.

In Rankine Cycle we use the concept of Tm(mean temperature of heat addition).In actual cycle the efficiency comes as n=1-T2/T1 Taking Tm into consideration it comes as n=1-T2/Tm as T1>Tm so the efficiency for both case will not same for a same cycle. Can anybody explain how it is possible? Advance appreciation for your effort.Thanks
