Abstract
As the microstructure has great effect on the mechanical properties of nodular graphite cast iron, mechanical properties of two kinds of nodular graphite cast iron with different microstructures were studied by in situ neutron diffraction during tensile deformation with a time of flight method. It showed that in a cast iron consisting of pearlite and ferrite, the soft phase ferrite was a main factor influencing the yield point, and the hard phase pearlite was a reason of higher work hardening. There was also work hardening in a cast iron with high ferrite fraction, which came from the different stress distribution between hard grain (200) and soft grain (110). However, the work hardening from grain strain was smaller than that caused by phase strain.
