In situ neutron diffraction was used to monitor martensitic transformation during cooling for a Fe-18Ni alloy and tensile behavior of martensite for a 22SiMn2TiB steel. Changes in the lattice parameters of austenite and martensite in the Fe-18Ni alloy during cooling, were used to discuss the phase stress formed by martensitic transformation. Changes in the dislocation density, character and arrangement of martensite during tensile loading in the 22SiMn2TiB steel were used to discuss the deformation mechanism of martensite steel.
