摘要：
The method of nano-indentation is used to study the microhardness and modulus of elasticity of cementite in the structure of granular pearlite in the initial condition (after spheroidizing annealing) and after cold plastic deformation with epsilon = 34% and epsilon = 65%. It is shown that both characteristics of the cementite vary non-monotonically with an increase in strain. The results are compared with electron microscope data on the evolution of the deformed structure of granular pearlite.
