| Research Abstract |
Strength and reliability like toughness are strongly influenced by microstructure in engineering materials, so that novel processing for microstructure control is a key issue to develop new structural materials. Neutron scattering is a new tool to make clear microstructure evolution during material processing. A dilatometer which has been usually used for phase transformation was made to install in a new neutron instrument at J-PARC to measure Bragg diffraction as well as small angle scattering. Phase transformation and precipitation behavior in advanced steels were examined and many new findings were obtained.
